The main uses of rutile include extracting titanium, manufacturing titanium alloys, titanium dioxide (also known as titania white), sponge titanium, welding electrode coatings, etc. Rutile is a relatively pure form of titanium dioxide, typically containing over 95% TiO2, and is an important mineral raw material for refining titanium. It possesses 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, chemicals, seawater desalination, and other fields. Rutile itself is one of the essential raw materials for high-grade welding electrodes and is also the best raw material for producing rutile-type titanium dioxide pigments. Furthermore, the TiO2 in rutile is widely used in photocatalytic materials, where its unique capture and adsorption capabilities effectively purify indoor air without causing secondary pollution.
