Research on extracting titanor tetrachloride by chloridizing molten salts in titanor slay of new process

Based on the new process of extracting vanadium after steel melting and titanor slay it produced, the technology of extracting titanor tetrachloride by chloridizing molten salts was systematically studied, such parameters as chloridizing reaction temperature, initial salts system, components of reducer, chlorine concentration and its retrieving and reusing being optimized. The results showed that it was technologically and economically feasible to deal with titanor slay of new process through chloridizing molten salts; furthermore,the products of titanor tetrachloride had a high degree of purity. This research provides technological and economical basis for the follow-up industrial experiments.
