| Research Abstract |
The current process of mass production of titanium is based on the Kroll process. This process involves the use of titanium tetrachloride (TiCl_4) as a feed material, and a huge amount of heat is generated during the reduction process. For this reason, it is impossible to increase the reduction speed even when the most advanced modern large-scale reduction facilities are used. Furthermore, it is difficult to establish a continuous reduction process, and it is also difficult to avoid contamination of iron into the product from a reaction container. In order to solve the current problems in the titanium production process that is based on metallothermic reduction, a new process of high-speed titanium reduction using titanium subhalide as a feed material was studied.
