日本东京大学研究出一种精炼钛的新方法.据称,新方法的耗电量仅为现行方法的22%,且不需制成海绵钛,使工艺过程缩短一半,因而可大幅度降低生产成本.由于钛和氧的结合能力很强,因此难以精炼.目前常用的方法是先将氧化钛烧结成海绵钛,再把海绵钛用真空电弧炉熔炼脱氧,铸成钛锭.但是,传统方法需要腐蚀性很强的氯气.管理比较麻烦,而且耗电量较大,生产1吨海绵钛需要1.6万kW·h的 A new method of refining titanium has been developed at the University of Tokyo, Japan, and the new method reportedly consumes only 22% of the current method and does not require the production of titanium sponge, reducing the process by half and thus drastically reducing production Cost .Because titanium and oxygen binding ability is very strong, so it is difficult to refine the current common method is to first titanium oxide sintered into titanium sponge, and then sponge titanium vacuum arc furnace smelting deoxidation, cast into titanium ingot.However, the traditional method Need a very corrosive chlorine management is too much trouble, and power consumption, the production of 1 ton of titanium sponge needs 16,000 kW · h
