我国钛资源分布和生产现状

钛及其合金具有比强度高、耐蚀性能优、生物相容性好等优点，是一种战略金属，主要用于航空、航天、航海等先进装备。钛白粉是一种重要的化工原料。人造金红石高钛渣、天然金红石等富钛料是生产钛白粉电焊条和海绵钛的原料。本文概述了我国钛矿物的地理分布和由钛原矿到海绵钛的生产工艺，并与国外技术进行了对比说明。介绍了我国钛精矿、富钛料的产能、生产现状和国内需求情况。

Distribution and Production Status of Titanium Resources in China

Titanium and its alloys are mainly used for the advanced equipments of aircraft, aerospace and marine applications due to high specific strength, superior corrossion resistance and good biocompatibility etc. Titanium pigment is an important raw material in chemistry industry. Titanium pigment, electric welding bar and titanium sponge are made from raw materials which are rich in titanium such as synthetic rutile and titanium slag etc. Titanium resources are very abundant in China, coming out in front and China has dominant position in titanium resources. The geographical distribution and production processes from titanium crude ores to titanium sponge were summarized and also compared with foreign technologies. The paper briefly introduces the capacity, production status and demand of ilmenite concentrates and raw materials which are rich in titanium in China.
