1. Paints and Coatings Due to its excellent opacity and brightness, anatase TiO2 is extensively used as a pigment in paints. The high refractive index of this compound allows for better coverage and durability, making it an essential component in decorative and protective coatings.
Most food-grade titanium dioxide is around 200–300 nanometers (nm) in diameter. This size allows for ideal light scattering, resulting in the best color (1Trusted Source).
