TiO2 has large refractive index and can get high birefringence. It is an ideal material for making spectroscope prism and polarizing devices (opto-isolator and beam splitter). Compared with YVO4 crystal, TiO2 crystal has better physical and chemical stability. 
With high gloss, good whiteness, good dispersibility, good liquidity, extraordinary hiding power and good coloring power, good weather resisting property and chalk resistance performance, TiO2 has been widely used in various fields, such as decorative coatings, powder coatings, coatings used in the general industry and other industries. It also is applicable to the printing ink, Paints, paper-making, plastic color master batches, PVC, the plastic steel, sectional materials, tubes and pipes, Rubber, polyvinyl chloride, polystyrene, polyolefin, engineering plastics and so on.
