Appearance and properties: white solid or powder form of gender oxide; is an insoluble compound. Exist in nature there are three variants of titanium dioxide: rutile, tetragonal crystals; anatase tetragonal crystal; brookite orthorhombic crystals. Titanium dioxide solubility in water is small, but can be dissolved in acid, can also be dissolved in alkali. Role: Titanium dioxide is considered the world's best performance of a white pigment widely used in paints, plastics, paper, printing ink, chemical fiber, rubber, cosmetics and other industrial Titanium dioxide in the rubber industry, both as a coloring agent, but also has been strengthened, anti-aging, filling the role. In the white and colored rubber products by adding titanium dioxide, in the bright sunlight, sunlight-resistant, non-cracking, do not change color, stretch rate is high and the acid and alkali. The application of titanium dioxide in cosmetics are becoming increasingly widespread. Because titanium dioxide non-toxic, than the white lead is superior, all kinds of titanium dioxide powder used to replace almost all of white lead and zinc white. A variety of other spices, sunscreen, soap flakes, white soap and toothpaste can also be used in the titanium dioxide. Titanium dioxide in enamel with the transparency of the system was strong, with the quality of small, strong impact resistance, mechanical performance is good, colorful and difficult to pollution, and so on. Food and pharmaceutical use of high purity titanium dioxide, heavy metals content is low, hiding power and strong titanium dioxide
