Preparation of Titanium Subchloride and its Electrodeposit in Chloride Melts

摘要：

This work proposed a process to prepare titanium subchlorides by using titanium and titanium tetrachloride as raw materials in an equimolar ratio of KCl-NaCl melt. According to the reactions Ti4+ +Ti→2Ti2+ ,Ti4+ +Ti2+→2Ti3+ ,different molar ra:io of Ti2+ /Ti3+ titanium subchlordie salts could be prepared by controlling the ratio of raw materials. And the concentration of Ti2+ can be measured by the molar mass of hydrogen based on the reaction,Ti2+ + H+(←→)Ti3+ + l/2H2. The total titanium chloride concentration was measured by the Diantipyryl Methane Photometric method.The prepared titanium subchloride was used as electro-activation ions for the titanium deposits in KCl-NaCl melts at 720℃.
