Low-Melting CaCl2-NaCl-Al2O3 Electrolyte for Direct Electrochemical Reduction Solid Al2O3
The electrical conductivity and density of the low-melting CaCl2-NaCl-Al2O3 systems at 550°C~800°C ranges were respectively measured by the Continuously Varying Cell Constant Technique, ac-techniques and Archimedes method. The materials were applied as the electrolyte for the direct electrochemical reduction solid Al2O3 at 550°C ~800°C. The materials were composed of 71wt.%~87wt.%CaCl2 (corresp...
متن کاملThe Electrochemical Behavior of Al Alloys in NaCl Solution in the Presence of Pyrazole Derivative
This paper studies the corrosion inhibition of Al-Mg alloy system in 0.5 mol/dm3 NaCl solution in the presence of pyrazole derivative using potentiodynamic polarization and linear polarization method. The inhibition efficiency as a function of concentration and temperature was investigated. From the polarization curves, it can be concluded that the pyrazole derivative be...
متن کاملHigh energy transmission of Al2O3 doped with light transition metals.
The transmission of transparent colored ceramics based on Al(2)O(3) doped with light transition metals is measured in the visible and infrared range. To clarify the role of the dopands we perform ab initio calculations. We discuss the electronic structure and present optical spectra obtained in the independent particle approximation. We argue that the gross spectral features of Co- and Ni-doped...
متن کاملElectrochemical Behavior of Nanocrystalline Fe88Si12 Alloy in 3.5% NaCl Solution
Influence of microstructure on electrochemical behavior of nanocrystalline Fe88Si12 alloy has been investigated in 3.5 wt% NaCl solution. The results show that Fe88Si12 alloy with optimal corrosion resistance is composite of ordered Fe3Si and disordered Fe(Si) phases and grain size of 40 nm. Because the ordered Fe3Si structure is beneficial to form SiO2 film, which possesses good corrosion resi...
متن کاملSolubility of corundum in the system Al2O3–SiO2–H2O–NaCl at 800 °C and 10 kbar
The solubility of corundum was measured at 800 °C and 10 kbar in NaCl–H2O–SiO2 fluids over NaCl mole fractions (XNaCl) of 0 to 0.5 and SiO2 concentrations of zero to quartz or albite+melt saturation, depending on XNaCl. Experiments were performed in a piston-cylinder apparatus. Dissolved Al2O3 and SiO2 were determined by weight losses of corundum and quartz crystals, or by bulk compositions of ...
