Most widely used pigment in paint manufacturing industry – Titanium Oxide (TiO2)

Titanium dioxide, also called titania, (TiO₂), a white, opaque, naturally occurring mineral existing in a number of crystalline forms, the most important of which are Rutile and Anatase. Anatase TiO₂ changes to Rulite above 800 °C.

Titanium dioxide pigment is a fine white powder. When used in paints, it provides for maximum whiteness and opacity. … It does this more effectively than any other white pigment. Today, Titanium dioxide pigment is by far the most important material used by the paints manufacturing industry for whiteness and opacity.
These naturally occurring oxide forms can be mined and serve as a source for commercial titanium. Titanium dioxide is odourless and absorbent. Its most important function in powder form is as a widely used pigment for lending whiteness and opacity.
