| Abstract Scope |
The wider application of titanium is restricted by its expensive price due to high-cost production of Kroll process. The process of molten salt electrolysis with soluble anode is proposed by Zhu and Jiao in 2005, whereas titanium oxycarbide (TiCxO1-x) as soluble anode dissolves into titanium ion in electrolyte of molten chlorides, and metallic titanium with purity of 99.5% and impurity of oxygen lower than 300 ppm deposits in cathode. Moreover, TiCxO1-x can be synthesized through selective carbothermic reduction of ilmenite followed with magnetic separation and acid leaching for concentration. The overall process for titanium production will lead to the cost reduction by half referring to Kroll process. |
