Rutile, the most common form of titanium dioxide, is a reddish-brown pigment with a high refractive index and excellent weathering resistance. It is mainly used in paints, coatings, plastics, and paper industries due to its ability to provide excellent whiteness, opacity, and UV protection. Rutile titanium dioxide is typically produced by the sulfate process, which involves the reaction of titanium ore with sulfuric acid to produce titanium sulfate. The resulting solution is then treated with ammonia to precipitate titanium hydroxide, which is subsequently calcined at high temperatures to obtain rutile titanium dioxide.

Lithopone, C.I. Pigment White 5, is a mixture of inorganic compounds, widely used as a white pigment powder. It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. It was made popular by the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide (zinc white), zinc sulfide, and white lead.[1]
