Rutile is a relatively pure titanium dioxide, generally containing over 94% titanium dioxide, and is an important mineral raw material for extracting titanium. Rutile has excellent properties such as high temperature resistance, low temperature resistance, corrosion resistance, high strength, and low specific gravity, and is widely used in military aviation, aerospace, navigation, machinery, chemical industry, seawater desalination, and other fields. Rutile itself is one of the necessary raw materials for high-end welding electrodes and also the raw material for producing rutile type titanium dioxide.
