Full textThe compositional domain Ca(ZrxTi1-x)O3 has been studied in order to understand the formation of solid solution between CaTiO3 and CaZrO3. The aim of this study is the application of such formulations for multilayer ceramic capacitors with non-nobles metal armatures. The synthesis on the line CaTiO3/CaZrO3 is poorly known, either by solid state or by flash-combustion. The study and optimization (mixing/grinding, temperature of calcination) of the solid-state synthesis has allowed the synthesis of single-phase samples made of the perovskite phase along the whole compositional range. The study of the solution-combustion synthesis first determined that the most efficient fuel for the synthesis was glycine, then the fact that the titanium input allowing the formation of the purest phase is TiO(NO3)2, synthesized from titanium butoxide.The densification of the powders obtained by these two methods was studied and compared. These tests allowed to compare several parameters on the densification of the samples. These parameters are the powders’ method of elaboration, the Zr/Ti ratio and the sintering atmosphere. Sintering adds were also be tested on two compositions: CaZrO3 and Ca(Zr0.8Ti0.2)O3. These compositions have been chosen because they are weak in titanium, which avoids reduction and appearance of semi-conduction of Ti that would transform the capacitor into a p-semiconductor during sintering in a reducing atmosphere. This comparative study of these different parameters also deals with the dielectric properties of the samples thus produced

Full textLaNi5 (CaCu5-type structure) is one of the most studied intermetallic compounds for hydrogen storage. The substitution of nickel or lanthanum by other elements changes the hydrogenation properties. A geometrical model relates the volume of the intermetallic compound and the enthalpy of formation of the hydrides: the bigger is the volume, the more stable is the hydride. Though, platinum substitution contradicts this model. To explain this behaviour, the substitution of nickel by atoms M (M=Ru, Rh, Pd, Ag, Re, Os, Ir, Au), neighbours of platinum and their effects on hydrogenation properties were investigated. The solubility limits of the M elements are established and the phases in equilibrium with the CaCu5 phase are characterized. These elements change drastically the hydrogenation properties: like platinum, these compounds contradict the geometrical model. To understand the phenomena occurring in these compounds, neutron powder diffraction experiments were conducted on the LaNi5-xPdx-D2 system. The hydrogenation is performed in situ and allows drawing the LaNi5-xPdx-D2 phase diagram. The hydride structures have been studied : partial ordering of deuterium and/or nickel atoms leads to different superstructures of the CaCu5-type structure. The causes for theses anomalies are also investigated by examining the electronic structure of the intermetallics and their hydrides. Ab initio calculation methods are used in agreement with the experimental results. We have shown that the instability of the dydrides is connected to the strong stabilization of the intermetallic compounds due to the M element

Full textThis thesis concerns the experimental study and thermodynamic modeling of the behavior of advanced fuels used in current and future generation nuclear power plants. The subject of the thesis is more precisely the study of the ternary system (U-Nd-O) and for comparison purposes of (U-Ce-O). This system is particularly representative of the fission products accumulated in the fuel for high combustion rates but also of the initial atomic substitutions in the fuel by neutron poisons, used in nuclear fuels with high enrichment levels and capable of spacing out nuclear reactor outages. The study of this system presents significant challenges due to the open conflict between thermodynamic and kinetic phenomena. It is indeed an out of equilibrium system where the long-range ordering of local structures is frustrated by the negligible of atomic transport in the cation sublattice in the range of temperatures of interest for applications. During this thesis, a review of the existing literature motivated the manufacture of samples with well-defined characteristics by powder metallurgy methods and by soft chemistry methods leading to a control of dopant distributions. The results obtained by numerous characterization techniques (XRD, SEM, TEM, XAS) on samples treated thermally under oxidizing or reducing conditions have allowed a critical re-evaluation of the phase diagrams currently used. We have modelled a new phase diagram that includes new experimental results. This allows a better knowledge of the limits of use of nuclear fuels respecting optimal safety conditions

Full textLa2Mo2O9, the first compound in the LAMOX family, is interesting for its applications as electrolytes in fuel cells because it presents a high ionic conductivity. It was discovered during the investigation of La2O3 - MoO3phase diagram. That shows the important role of phase diagram study in the discovery of new materials which has become a major objective of many solid chemists.In this concept, two ternary phase diagrams of La2O3-Nb2O5-WO3 and La2O3-Nb2O5-MoO3 were explored and analyzed for the first time using the solid-state synthesis. The structures of the obtained samples were characterized by the powder X-ray and neutron diffraction and by the transmission electronic microscopy. Besides, their electric properties were tested by the complex impedance spectroscopy onsintered pellets.As results, most of the mono-, bi-, tri-phase zones in the title phase diagrams have been defined. Particularly, during the phase-diagram investigation, the structures of two new phases La3NbWO10 and La5NbMo2O16 were ab-initio resolved. Firstly, the La3NbWO10 cell is asuperstructure of a fluorine (2aF*2aF*2aF) with the lengthened c axis. Considering the La18Nb6W62O604(Z = 6) formulation, we can easily note that the structure presents 2 types of defaults: cationic and anionic vacancies. Secondly, the La5NbMo2O16 phase is isotype of Pr5Mo3O16 compound. Its cell is also a fluorine superstruture. It crystallized in a cubic system (a = 11.22Å) with the space group Pn n. The compound is promising because it presents an oxygen conductivity comparable to that of La2Mo2O9 at low temperature

Full textThe nuclear energy represents today an important fraction of electricity production in the world and especially in France. The most used nuclear fuel today is the uranium dioxide UO2. In this thesis, we have studied the crystallographic structure evolution of this material related to the increase of its burn-up.We have confirmed that, under conditions similar of those of irradiated nuclear fuel, a miscibility gap exists in the (U1-yNdy)O2 system. As (U1-yNdy)O2 system can be considered as a model of the fuel, we have search for the existence of a miscibility gap in the irradiated fuel, which would be considered as a ternary pseudo diagram de phases. XRD measurements of theses system give us results consistent with this hypothesis.Based on this evidence, we propose a new interpretation of the microstructure evolution of the irradiated fuel as a function of the burn-up

Full textAmericium isotopes are the main contributors to the long-term radiotoxicity of the nuclear wastes, after the plutonium extraction. Among the reprocessing scenarios, the transmutation in fast neutron reactors using uranium-americium mixed oxide (U,Am)O2±x pellets seems promising. In this frame, the knowledge of the thermodynamics of the U-Am-O ternary system is of essential for the prediction of the behavior of (U,Am)O2 pellets and their possible interaction with the cladding, under normal and accidental conditions. This thesis is dedicated to the experimental investigation of U-Am mixed oxides on a wide range of Am contents (7.5 at.% ≤ Am/(Am+U) ≤ 70 at.%), with the aim to collect data for developing a thermodynamic model based on the semi-empirical CALPHAD method. The obtained results can be classified in three categories: structural, phase diagram and thermodynamic data. For the thermodynamic modeling of the ternary system, the assessment of the binary sub-systems is first required. As open questions still existed on the Am-O system, a first part of the work was dedicated to the study of the Am-O phase diagram by high-temperature (HT) XRD. The existence of a composition range of the bcc AmO1.61 phase was highlighted and the miscibility gap in the fluorite phase, proposed in the literature, was not found. Thanks to the new experimental data, the existing CALPHAD model of Gotcu et al. was modified. In a second step, structural investigations were performed on synthesized (U,Am)O2±x dioxides by coupling XRD, XAS and Raman spectroscopy. For all the compositions, the XRD confirmed the formation of a single fluorite structure. The O/M ratio (with M=U+Am) at room temperature was determined to be lower than 2; the stability of trivalent americium Am3+ in the dioxide solid solution was highlighted, which induces a partial oxidation of uranium from U4+ to U5+. This charge distribution, peculiar for a dioxide, is accompanied by the formation of complex oxygen defects in the fluorite structure. By a HT-XRD investigation of the mixed oxides under air combined with XAS characterization of the oxidized samples, it was shown that the presence of Am3+ leads to a stabilization of the dioxide fluorite phase toward the formation of oxides richer in oxygen, in comparison to the U-O system. New phase diagram data were obtained in the oxygen rich region at 1470 K: tie-lines in the M4O9-M3O8 and MO2+x-M3O8 domains were determined and the solubility of americium in the M4O9 and M3O8 oxides was estimated. The investigation of the U-Am-O phase diagram continued at higher temperature with the study of the solidus/liquidus transitions using a laser-heating technique, under argon and air, and post-melting characterizations conducted by SEM and XAS. The melting temperature of Am-U dioxides decreases with the increase of both the Am/(Am+U) and O/M ratios. Finally, thermodynamic properties of the U1-yAmyO2±x oxides were measured: enthalpy increments using drop calorimetry, partial vapor pressures by Knudsen cell effusion mass spectrometry (KEMS). An excess contribution to the heat capacity at high temperature was observed and this was attributed to the reduction of the dioxides at high temperature (formation of oxygen vacancies). The KEMS results lead to determine the congruent vaporization composition at 2300 K, for a Am/(Am+U) ratio of 0.6 and an O/M ratio lower than 1.9. Finally, the CALPHAD thermodynamic assessment of the U-Am-O system was started, by focusing the attention on the modelling of the fluorite phase. A good agreement between the model and the oxygen potential data for (U0.5Am0.5O2±x) and the cation distribution was achieved. Furthermore, the model is able to satisfactorily reproduce the KEMS data and hence the equilibrium between the dioxide and gas phase. For the perspectives of this work, the optimization of the thermodynamic model should be extended to describe the phase equilibria involving the M4O9, M3O8 oxides and the liquid phase

Full textZrCr2, par exemple, possède une grande capacité de stockage de l'hydrogène mais une pression d'équilibre de formation de l'hydrure trop faible pour l'application. De plus, le milieu électrolytique (potasse concentrée) provoque une passivation du matériau bloquant les mécanismes électrochimiques.
L'étude porte d'une part sur l'adaptation des propriétés thermodynamiques d'hydrogénation à l'application électrochimique du composé ZrCr2 par substitution du chrome par le nickel et d'autre part sur la modification des propriétés de surface de la phase par précipitation de phases secondaires en équilibre avec la phase de Laves.
Pour cela, le diagramme d'équilibre Zr-Ni-Cr a été déterminé à 1000°C dans la région ZrCr2-ZrNi-Ni-Cr et a mis en évidence la très large solubilité du nickel dans les phases de Laves de type C14 et C15 ainsi que les équilibres de ces phases avec trois phases du système binaire Zr-Ni. La connaissance de ce diagramme a permis la synthèse d'alliages biphasés où la phase de Laves de composition constante est en équilibre avec un taux variable de phases secondaires.
L'étude des propriétés d'hydrogénation des phases de Laves montre la possibilité d'adapter la pression d'équilibre de leurs hydrures à l'application électrochimique tout en conservant une grande capacité d'hydrogénation. Les propriétés d'hydrogénation des phases secondaires ont par ailleurs été caractérisées.
Enfin, la précipitation des phases secondaires en proportion croissante dans une matrice de phase de Laves à composition constante apporte une amélioration très substantielle des capacités électrochimiques. Un tel effet est interprété par la modification de la nature de la surface en contact avec l'électrolyte et par le transfert de l'hydrogène de l'électrolyte vers la phase de Laves à travers la phase secondaire quand elle est présente.

Full textTwo main research axes were defined for this Ph-D work : (i) studying the effect of light elements (B, C) on the stability of U-Si compounds, and (ii) identifying and physically characterizing new phases in the U-Pt-Si system. Minor additions of carbon and boron in U-Si samples revealed that the formation of U₅Si₄ would be correlated to the presence of these light elements, questioning its existence in the U-Si system. To evaluate the boron potential as a stimulant for non-metallic light elements of the second period (C, N, O), the isothermal section of the ternary phase diagram U-Si-B has been drawn at 927 °C, disclosing solid equilibrium mainly between the U-B and U-Si binary axes and the existence of the novel compound U₂₀Si₁₆B₃, isostructural to the carbon equivalent one. These results suggest a specific behavior for a given light element on the U-Si phase relations. The isothermal section at 900 °C of the U-Pt-Si ternary system was experimentally determined, leading to the discovery of 14 new phases, among which U₃Pt₄Si₆, U₃Pt₆Si₄ and U₃Pt7Si crystallized in their own structural type. As a prerequisite for this study, the phase relations in the U-Pt binary phase diagram were re-examined for the composition range 30 at.% and 70 at.% Pt, leading to a new assessment of the phase diagram which comprises the new U₃Pt₄ compound . The temperature of the transformations has been measured by DTA. By coupling our experimental results to the literature data, a modeling of the phase diagram by the Calphad method was performed. Physical characterizations of the new U₃Pt₄ compound revealed a moderate heavy fermion behavior, with ferromagnetic ordering below Tc = 7(1) K. As a side project, a study of the U₃TGe₅ family with the anti-Hf₅CuSn₃ structural type lead to the discovery of nine new compounds for T = V, Cr, Mn, Zr, Nb, Mo, Hf, Ta and W in addition to the previously reported U₃TiGe₅. Their magnetic and electronic properties were evaluated, disclosing moderate heavy-fermion compounds, with behavior evolving with valence electron count of the transition metal. For T = Ti, V compounds, correlation between spin and charge density waves are suspected below the magnetic ordering temperature

Full textDue to their physical and chemical properties, mixed uranium-plutonium oxides are considered for fuel in 4th generation nuclear reactors. In this frame, complementary experimental studies are necessary to develop a better understanding of the phenomena that take place during fabrication and operation in the reactor. The focus of this work was to study the U Pu–O phase diagram in a wide range of compositions and temperatures to ameliorate our knowledge of the phase equilibria in this system. Most of experiments were done using in situ X-ray diffraction at elevated temperatures. The control of the oxygen partial pressure during the treatments made it possible to change the oxygen stoichiometry of the sample, which gave us an opportunity to study rapidly different compositions and the processes involved. The experimental approach was coupled with thermodynamic modeling using the CALPHAD method, to precisely plan the experiments and interpret the obtained results. This approach enabled us to enhance the knowledge of phase equilibria in the U–Pu–O system

Full textIn recent decades, the study of intermetallic compounds containing 3d transition metals and 4f rare earth elements presents great interest both from a fundamental point of view and in its various applications. The remarkable properties of these magnetic materials come from the presence, in the same compound, of 3d transition metal, characterized by an itinerant magnetism given by the electrons in the 3d external band, and 4f rare-earth which themselves have a localized magnetism due to the electrons of the 4f inner layer. The research presented here will focus on the construction of two ternary phase diagrams combining [Sm-Fe-Ni] in the first system and [Y-Fe-Ga] in the second one. These types of intermetallics are also characterized by a magnetocaloric effect (EMC) defined by the heating or cooling of these magnetic materials under the application or removal of an external magnetic field.The aims of the thesis are the construction of two ternary phase diagrams that have never been published before and the study of the physicochemical properties in the (Sm, Y) -Fe- (Ni, Ga) systems. This research will lead to the determination of experimental ternary phase diagrams Sm-Fe-Ni and Y-Fe-Ga (isothermal section at 800°C) and to study the structural properties of some intermetallic compounds.The magnetic and magnetocaloric properties were also studied by coupling magnetic analysis with the X-ray diffraction and Mössbauer spectroscopy measurements. This work has highlighted the important influence of the nature and rate of iron substituted by nickel and gallium in both systems on the magnetic properties

Several samples with different compositions have been prepared by sputtering. Aluminium, copper and iron layers were deposited onto oxidized silicon substrates, they were heat treated and characterized by using several techniques. In situ X-ray diffraction and resistivity measurements were used to follow the phase formation. Thermal annealings followed by quenching have also been carried out to get additional information.Differential Scanning Calorimetry and coupled in-situ resistivity and X-ray diffractionmeasurements were performed. The whole results allowed us to suggest a mechanism of phase formation for each sample and by using theoretical models of growth we determined kinetic data on the phase formation
