Titanium dioxide is the most widely used white pigment because of its brightness and very high refractive index.

Titanium dioxide crystal size is ideally around 220 nm (measured by electron microscope) to optimize the maximum reflection of visible light.

The optical properties of the finished pigment are highly sensitive to purity.


The most important application areas are paints and varnishes as well as paper and plastics, printing inks, fibers, rubber, cosmetic products, and food.
