Progress in the Research of Titanium Sponge Processes

Titanium has many desirable properties (high specific strength and high corrosion-resistance). Titanium metal is a sort of product with promising market. Hunter process disappeared completely in 1993. The most widespread titanium sponge process is Kroll process (magnesium reduction). Its shortcomings (complicated route, high cost and serious pollution) are obvious although it is the most mature technology. The most advanced came up in UK, 1998. It is characterized by low cost, excellent product, short route and extensive adaptability, and is a type of high cleanness process. Compared with other processes, this electrolyzing process for the direct reduction of TiO 2 represents the tendency of titanium metal making in the future, and should be applicable to a wide range of metal oxides.
