Titanium dioxide (TiO2) is an important inorganic chemical product, which has important applications in coatings, inks, paper, plastics, chemicals, ceramics and other industries. The main component of titanium dioxide is a white pigment of titanium dioxide (TiO2). The molecular formula is TiO2, which is a polycrystalline compound whose particles are regularly arranged and have a lattice structure. Titanium dioxide has the lowest relative density. The production process of titanium dioxide has two routes of sulfuric acid method and chlorination method.
