金红石是就是较纯的二氧化钛，一般含二氧化钛在95%以上，是提炼钛的重要矿物原料，但在地壳中储量较少。它具有耐高温、耐低温、耐腐蚀、高强度、小比重等优异性能，被广泛用于军工航空、航天、航海、机械、化工、海水淡化等方面。金红石本身是高档电焊条必须的原料之一，也是生产金红石型钛白粉的最佳原料。
Rutile is pure titanium dioxide, which generally contains more than 95% of titanium dioxide. It is an important mineral raw material for titanium extraction, but it has less reserves in the crust. It has high temperature resistance, low temperature resistance, corrosion resistance, high strength, small specific gravity and other excellent properties, and is widely used in military aviation, aerospace, navigation, machinery, chemical industry, seawater desalination and so on. Rutile itself is one of the necessary raw materials for high-grade electrodes, and also the best raw material for producing rutile titanium dioxide.
