总结了人造金红石和海绵钛生产现状及存在的主要问题，讨论了制约钛生产的关键，对加压浸出制备人造金红石进行了试验研究，得到了纯度大于96%的人造金红石，并开展了熔盐电解制备海绵钛的试验研究。

This paper summarizes the status and problems of production of synthetic rutile and sponge titanium and discusses the restricting factors of titanium production. Experiments have been, conducted on preparation of synthetic rutile by pressure leaching and the content of TiO₂ of the rutile is more than 96%. The production of sponge titanium by molten-salt electrolysis is under research.
