Based on ti02 has a high refractive index, strong achromatic power, covering power, good weather resistance, strong dispersion, good luster, physical and chemical stability and many other excellent characteristics, so it is the largest amount, the best quality, the most widely used white pigment. It is an indispensable raw material in electronics, chemical, light industry and metallurgy industries, and is an important chemical product with a wide range of application prospects.

Ink is a kind of viscous fluid composed of color material, filler, additive and color developing agent. At present, printing newspapers, books, pictures and printing iron, printing metal, printing porcelain, printing rubber, printing plastic and printing radio semiconductor circuit boards are inseparable from ink. Because titanium dioxide has a large hiding power, high color dissipation power, fine particles, dilute acid dilute alkali resistance, light resistance, heat resistance, not easy to yellowing, good hydrophobicity, small fluidity, insoluble in color development agent and can be evenly dispersed in color development agent, it is an indispensable color material for advanced white ink and light color ink.
