Investigation Of The Direct Electrochemical Reduction Of Cr_(2)O_(3) Powder In Molten Cacl_(2) By A Metallic Cavity Electrode, Guo-Hong Qiu, Di-Hua Wang, Xian-Bo Jin, Xiao-Hong Hu, Zheng Chen
Journal of Electrochemistry
A metallic cavity electrode is used for further investigation of the electrochemical behaviour of(Cr_(2)O_3) powder in molten CaCl_(2)(Na: ~0.02% by mass,Mg: < 0.005% by mass) at 900 ℃.The Cr_(2)O_(3) powder reduction mechanism was confirmed in line with EDX and SEM analysis of the potentiostatic electrolysis products.The correlations between the particle size of metallised product and the electrolysis potential,or electrolysis time were analysed.
