Titanium dioxide - TiO2

What is Titanium dioxide (TiO2)?

Titanium dioxide is a chemical compound with a chemical formula TiO2. It is composed of a barium cation and the sulfate anion. The sulfur is attached to four oxygen atoms. TiO2 is a sulfate salt of barium and is found as mineral barite. It is a crystalline solid white in colour which is insoluble in water and alcohol but soluble in concentrated acids. It is odourless. Titanium dioxide is an alkaline, divalent metal. It is non-toxic and is safe for medical use. It is widely used in the production of oil and natural gas to get high-density drilling fluids by keeping the boreholes free of rock.
