Abstract:
Liquidus temperature, electrical conductivity and phase composition of Al2O3-CaO-Na2CO3 slag were studied in the paper. The results showed that the minimum value of liquidus temperature was 1429°C when the content of Na2CO3 was 11%. The Al2O3-CaO-Na2CO3 slag of lower liquidus temperature had higher electrical conductivity, and the electrical conductivity of Al2O3-CaO-Na2CO3 slag increased with the increase of temperature. The main phases of Al2O3-CaO-Na2CO3 slag are composed of CaAl2O4, Ca3Al10O18, NaAlO2 and Na2CO3. The addition of Na2CO3 is to be more effective for decreasing liquidus temper

AbstractFour different magnetic Fe3O4 nanoparticles were synthesized and characterized by solvothermal method based on different sodium salts. Sodium salts which were used to synthesize the nanoparticles were NaOAc, Na2CO3, a mixture of NaOAc and Na3Cit, and a mixture of NaOAc and Na2C2O4. The structural and optical properties of the synthesized nanoparticles were examined by XRF, XRD, SEM and FT-IR. The results estimated from XRD pattern and SEM image indicated that the second sample (Na2CO3) had the lowest average particle and crystallite size around 29 nm and 43 nm. It was also shown that t

Diffusion coefficients of Na2CO3 + H2O and NaHCO3 + H2O have been measured by a conductimetric technique at 25 °C. Above 0.1 mol L−1, diffusion of aqueous Na2CO3 is typical of a simple binary electrolyte. At lower concentrations a significant proportion of the Na2CO3 component diffuses as NaHCO3 and NaOH produced by hydrolysis: [Formula: see text]. Because OH− is more mobile than HCO3−, binary Na2CO3 + H2O solutions undergoing diffusion separate spontaneously into two ternary solutions: Na2CO3 + NaOH + H2O ahead of the diffusion boundary and Na2CO3 + NaHCO3 + H2O left behind the boundary.

Alkaline stress (AS) is one of the major threats that severely affects rice growth and grain yield. However, the differences in the damage caused by the main components of soda saline-alkali land, sodium carbonate (Na2CO3), and sodium bicarbonate (NaHCO3) to rice seedlings are still unclear. This study explored the effects of different carbonate stresses (Na2CO3 and NaHCO3) on rice seedling growth, root damage, physiological responses, and molecular changes. By administering equivalent concentrations of sodium ions through these different carbonate treatments, we observed that both stresses si

The sodium and vanadium levels are of major concern since they cause high temperature corrosion at temperatures over 500°C.

Abstract:
Abstract The resistance of commercial austenitic, ferritic, and duplex alloys to stress corrosion cracking in a 5%NaOH-2%Na2S-2%Na2CO3-0.2%Na2SO4-0.1%NaCl solution at 150 °C had been studied by immersion tests and electrochemical measurements. The effects of alloy composition, solution composition and test temperature on the occurrence of stress corrosion cracking were examined. It was found that either high chromium or high nickel contents were necessary to increase stress corrosion cracking resistance, and that the presence of sodium chloride, sodium carbonate, and sodium sulfate has little

Abstract:
Abstract Recently, several localized corrosion and cracking failures happened to API 5CT Grade C110 tubing in high-density formate completion fluid at high temperature, because of the leakage of CO2 and the mechanical damage on the tubing surface. In this paper, the hydrochemical simulation software is used to calculate the needed content of pH buffer. The corrosion behavior of C110 tubing was investigated with autoclave, scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results show that 1 wt% Na2CO3 and 1 wt% NaHCO3 can maintain the pH of formate completion fluid mixed with

Abstract The objective of this study was to determine the effect of digester liquor composition on the likelihood of stress corrosion cracking of steel under freely corroding conditions. Slow strain rate tests of A516gr70 pressure vessel steel in NaOH-Na2S- Na2CO3 solutions at 90 C under controlled potentials showed stress corrosion cracking in a narrow range of potentials centered on -890 mV (SCE) . The free corrosion potential (Ecorr) of this steel was measured for up to 28 days in 25 different solutions containing 20 to 80 g/l NaOH, 10 to 50 g/l Na2S, 3 to 11 g/l Na2S2O3, and 0 to 2 g/l So

Abstract Alloy 600, alloy 690 and alloy 800 were exposed to 10 and 50% caustic solutions containing 1% Na2CO3. Intergranular attack (IGA) reproducibly occurred in all three alloys in the 10% caustic solution at 350°C after a 240 h exposure and in the 50% caustic solution at 320°C after a 120 h exposure. IGA was not observed in mill-annealed plus thermally treated alloy 600 and alloy 690 after exposure to any of the test conditions. IGA was correlated with a dealloying mechanism in which the more active alloying metals, iron and chromium, selectively dissolve. Boric acid and calcium hydroxide a

Abstract:
Abstract The dissolution of transition metal oxides in molten carbonates is of interest for studies of hot corrosion and of the degradation of cathodes in molten salt fuel cells. This dissolution is generally believed to be a function of the basicity of the solvent salt, and consequently an understanding of the relationship between basicity and solubility of metal oxides is important. When the solvent is a mixture of salts, the basicity is regarded as a common ionic activity which satisfies the dissociation constants of both component carbonates.

Abstract In this communication, we will describe an integrated monoethylene (MEG)-reclaiming process using carbon steels metallurgy for most of the lines and vessels that handle MEG slurry solutions. Due to the potentially highly corrosive conditions in this type of facility, corrosion resistant alloys such as duplex stainless steels often constitute the preferred option for this process. The aim of this work is to check if carbon steels represent a viable alternative. Corrosion tests were conducted on carbon steel (UNS K02100) and a duplex stainless steel (UNS S32205) at 120°C in MEG solution

Abstract The effect of strain distribution on stress corrosion cracking (SCC) susceptibility of Inconel® Alloy 600 c-ring was investigated both in caustic (50% NaOH+ 1% Na2CO3 at 320°C) and acid (boiling 25% HNO3) exposures. By using the computer-aided x-ray rocking curve analysis method sampling a large grain population, the determination of strain distribution of laboratory c-ring deformed to closure was carried out as a function of the angular position along the periphery of the c-ring surface layer. The correlation between SCC susceptibility and applied strain was evaluated by scanning ele

The LaRonde Zone 5 (LZ5) mine is part of the Doyon-Bousquet-LaRonde mining camp and is located in the southern part of the Abitibi greenstone belt in northwestern Quebec. The LZ5 deposit consists of three stacked mineralized corridors: Zone 4, Zone 4.1, and Zone 5. Zones 4 and 4.1 are discontinuous satellite mineralized corridors, whereas Zone 5 represents the main mineralized body. The mineralized zones of the LZ5 deposit and adjacent Ellison property (Ellison A and B zones) are hosted in the strongly-deformed, 2699-2695 Ma transitional to calcalkaline, intermediate to felsic, volcanic and vo
