Titanium dioxide (TiO2) is an important inorganic chemical product with significant applications in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers, and ceramics. Titanium dioxide (English name: titanium dioxide) is a white pigment mainly composed of titanium dioxide (TiO2). The scientific name is titanium dioxide, and the molecular formula is TiO2. It is a polycrystalline compound with particles arranged in a regular pattern and a lattice structure. Titanium dioxide has the lowest relative density. There are two production processes for titanium dioxide: sulfuric acid method and chlorination method.
