Heat is relatively low, and the reaction proceeds three-dimensionally in a condensed phase. (2) Iron contamination is prevented using a titanium reactor. In the Kroll process, a titanium reactor cannot be used because TiCl4 reacts with titanium to form TiCl2. On the other hand, TiCl2 equilibrates with titanium metal, and a titanium reactor can be used in the subhalide reduction process. (3) Semi-continuous reduction with a small lot size is possible. Lastly, (4) effective utilization of titanium scraps as a raw material is possible for establishing an environmentally sound process.Extensive research has been ongoing to develop a next-generation titanium production method aimed at overcoming the low productivity of the Kroll process. However, no practical method replacing the Kroll process has been proposed to date. Therefore, a new reduction process has to be established to make titanium a “common metal” (Figure 10). This process should be high speed, energy efficient, low cost, and have a low environmental impact. A breakthrough in elemental technologies is anticipated.Fig. 10Scope of development in the titanium production industryFull size imageReal Picture of Titanium RecyclingTitanium recycling is generally considered to be the recycling of post-consumer titanium products. However, at present, such recycling is not a priority on the industrial scale as titanium is mainly used for long-life products, such as structural materials for aircraft frames and heat exchangers in power plants. Although the demand for these products is currently increasing, their lifetime is quite long, at over 10 years. Hence, the current volume of scrap generation is
