Abstract:
Abstract A number of A5M5O17 (A = Na, Ca, Sr, La, Nd, Sm, Gd, Dy, Yb; B = Ti, Nb, Ta) type compounds were prepared by a solid-state sintering route and characterized in terms of structure, microstructure and microwave dielectric properties. The compatibility of rare earths with mixed niobate/tantalate and titanate phases was investigated. The larger ionic radii mismatch resulted in the formation of pyrochlore and/or mixed phases while in other cases, pure A5M5O17 phase was formed. The samples exhibited relative permittivity in the range of 35 to 82, quality factor (Q × fo) = 897 GHz to 11946 G

Abstract:
AbstractPhases present in slags from Araxá (Brazil), Oka (Quebec) and Fen (Norway) resulting from the production of ferroniobium by the aluminothermic reduction of pyrochlore-group minerals are a function of composition of the pyrochlore feed and the diverse fluxes (CaO, CaF2) added to the alumina and iron oxide used in the reduction process. Absent from all slags investigated are Fe-bearing compounds. All of the slags are modally-dominated by prismatic crystals of β-alumina or hibonite, with a wide variety of Th-Ba-Ti-Nb-Al-oxide compounds and silico-aluminate glasses occurring in the interst

Abstract:
The electrical properties and phase transition behavior of the sodium niobate-based solid solution (1-x)Li0.12Na0.88NbO3-xNa0.91Ba0.09Nb0.91Ti0.09O3 [(1-x)LNN12-xNNBT9] ceramics were investigated. The lattice constant changes became discontinuitous between LNNBT0.5 and LNNBT0.7. Moreover, the peak dielectric constant of LNNBT0.7 is twice that of LNNBT0.5. X-ray diffraction analysis and dielectric study confirmed that the different crystal phases of what are LNN-type rhombohedral (x=0), LNN-type orthorhombic (x=0.1, 0.3 and 0.5), NNBT-type orthorhombic (x= 0.7 and 0.9) and NNBT-type tetragonal

Abstract:
The present Thesis explores a few novel anode materials for both lithium-ion and sodium-ion rechargeable batteries. A series of layered metal titanium niobates have been synthesised and their electrochemical energy storage properties, ion transport, and reaction mechanisms are studied in detail. Alkali-titanium niobates such as Li-Ti-niobate (and it’s sodium counterpart) store lithium (sodium) via the conventional intercalation mechanism. Detailed experimental and theoretical investigations reveal interesting and non trivial ion transport, which are found to be strongly correlated to the elect

Abstract:
During recent year, the photorefractive materials are attractive in many applications such as optical image processing and optical computing because they have more lower threshold power and easily realize phase conjugation Potassium sodium strontium barium niobate crystal is one of the best candidates. It has open structure and large structure tolerance for dopants with different valence There are two different ways to improve the photorefractive properties of the materials. 1) by adjusting the composition of materials and 2) doping cation ions. This paper is to describe the doping effects on
