摘要: 介绍了制备金属钛的传统方法:Kroll法、Hunter法及熔盐电解法的工艺原理和概况,同时介绍了在这些方法的基础上正在开发和改进的钛制备方法,包括导电体介入还原法、连续生产钛粉的Armstrong法和直接电化学还原TiO2的FFC剑桥工艺,分析了各种方法的机理及特点. 由此指出降低钛生产成本的新工艺发展方向是转变现有间歇的海绵钛生产工艺为连续的金属钛粉及其合金的生产工艺.

Abstract: The principles and general situations of the traditional processes for producing metallic titanium, e.g., the Kroll, Hunter and molten electrolysis processes, are summarized and the new processes based on the formers, i.e., the EMR, Armstrong and FFC Cambridge processes are introduced, in addition, their mechanisms and characteristics are also analyzed. It is pointed out that the development trend for lowering titanium production cost is to convert the existing periodic processes for titanium sponge to continuous process for titanium powder or its alloy.
