Applications of titanium dioxide other than pigment production are as follows:
Production of fiber optic products
Titanium dioxide, with a chemical purity of 99.9998%, is used in producing optical fiber products, medical equipment, and the radio-electronic industry. In manufacturing ultra-pure glasses, titanium dioxide serves as a purity reference.
Synthetic fibers and textiles
For matting twisted fibre.
Cosmetics
For protection against ultraviolet radiation in sunblock creams, for higher whitening effect of toothpastes, soaps, etc.
Food industry
For higher whitening effect in products, for protection of product package color (plastics) against ultraviolet radiation.
Pharmaceutical industry
For higher whitening effect in pharma products.
Printing paint
To increase weather resistance of coatings.
Catalyst
Photocatalyst and inert ceramic base material for active components.
Nanotechnology
Titanium dioxide nanopowders are used for air purification in cities, in producing nanofiber paper based on TiO2, in hydrogen energy, etc.
