Ultrafine Titanium Dioxide Powder XM-DHR966 is an important inorganic chemical pigment, the main component of which is titanium dioxide. There are two production processes of titanium dioxide: sulfuric acid process and chlorination process. It has important applications in coating, ink, papermaking, plastics, rubber, chemical fiber, ceramics and other industries.
