A new titanium production process using the magnesiothermic reduction of titanium subhalides employing a titanium reaction vessel was investigated. This study discusses the possibility of establishing a high-speed, semi-continuous process for the production of high-purity titanium. The titanium subhalide feed material, either titanium dichloride (TiCl 2) or titanium trichloride (TiCl 2), and the magnesium reductant were charged into a titanium reaction vessel, and the reaction vessel was heated in an argon gas atmosphere. The sample temperature rose monotonically to 973 K, after which it increased rapidly, implying that the magnesiothermic reduction of titanium subhalide proceeded at a high speed. After the reaction, excess magnesium and the reaction product, magnesium chloride (MgCl 2), were removed by leaching or draining and vacuum distillation. At this stage, titanium sponge with 99.8% purity was successfully obtained. The titanium reactor did not appear to be damaged and thus proved its suitability for the magnesiothermic reduction of titanium subhalides.
