Important titanium compounds are: titanium dioxide (TiO2), titanium tetrachloride (TiCl4), barium titanate (BaTiO3).
Pure titanium dioxide is white powder, is an excellent white pigment, trade name "titanium white". It has both the covering properties of lead white (PbCO3) and the durability of zinc white (ZnO). Therefore, titanium dioxide is often added to paint to make high-grade white paint.
Used in the paper industry as a filler in paper paddles.
As a matting agent for artificial fibers in the textile industry; In glass, ceramic, enamel industry as an additive to improve its performance; Used as a catalyst in many chemical reactions. With the development of chemical industry, titanium dioxide and titanium compounds as fine chemical products have very high added value and attractive prospect.
Titanium tetrachloride is a colorless liquid; Melting point 250K, boiling point 409K, pungent smell. It hydrolyzes easily in water or moist air and gives off a lot of white smoke.
