Direct Electrochemical Preparation of Chromium Powder in Molten Salts
Direct electrochemical reduction of Cr2O3 pellets in molten CaCl2-NaCl mixture salt was investigated by 3.0V applied potential for 12h at 550°C in the improved cell. The electrolysis products were characterized by SEM, EDS and XRD. This study showed that the reduction production was effected by the position of Cr2O3 pellets. Complete reduction of Cr2O3 pellets was achieved near the crucible. Incomplete reduction of Cr2O3 pellets was achieved near the anode and the complex compound was formed.
