Electrochemical Reduction of Yttrium Ions段淑贞,赵立忠,魏寿昆摘 要:<正> The cathodic electrode process of Y3+ ions on the Mo electrode in the LiCl-KCl molten... voltammogram.Theresults show that the reduction mechanism of Y3+ ion is Y3++3e=Y,a simple one-step process.The cathodicprocess is very close to a reversible process under lower scanning rates......
intensive. Some of the promising electrochemical processes of titanium extraction were reviewed and the results of laboratory scale experiments on electrochemical reduction of TiO2 granules were brought out. Some of the kinetic parameters of the reduction process were discussed while presenting the quality improvements achieved in the experimentation. Key words: electrochemical reduction; titanium......
