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.

钛的当前大规模生产过程基于kroll过程。该过程涉及将四氯化钛（TICL_4）用作饲料材料，并在还原过程中产生大量热量。因此，即使使用最先进的现代大规模减少设施，也不可能提高降低速度。此外，很难建立一个连续的还原过程，并且也很难避免从反应容器中铁污染到产物中。为了解决基于金属热降低的钛生产过程中的当前问题，这是研究了使用亚卤化钛作为饲料材料的高速钛降低的新过程。
