钛提取技术进展

对传统和新发展的各种钛提取技术的基本原理、工艺特点及进展进行了回顾.介绍了目前国内外正在开发或改进的钛生产工艺,其中包括二氧化钛的直接电化学还原法、Armstrong(ITP)法、钙热还原法、金属氢化物还原法、四氯化钛熔盐电解还原钛、SOM法等,指出新工艺在工业应用中存在的问题.作者认为:由于传统的Kroll法生产成本高,限制了钛的应用,只有开发新的、连续化的生产工艺,才能从根本上达到降低生产成本的目的.

Research Progress of Titanium Production Technology

The conventional technological processes, rationale, progress and some new technologies for production of titanium metal are reviewed. The researching and developing of new technologies are introduced, including direct electrochemical reduction of TiO2, ITP process, calciothermic reaction, molten salt electrolytic process, metal-hydride reduction and SOM process, and points out some problems of new processes. It is indicated that the use of titanium is restricted because of its high processing cost and only...
