Titanium dioxide (English name: titanium dioxide) is a white pigment whose main component is titanium dioxide. The scientific name is titanium dioxide, and the molecular formula is TiO2, which is a polycrystalline compound with regularly arranged particles and lattice structure. The relative density of titanium dioxide is the smallest. There are two production processes of titanium dioxide: sulfuric acid process and chlorination process.
