TItanium Dioxide

White solid or powder form of gender oxides. Also known as titanium dioxide. Chemical formula TiO2, molecular weight 79.9, melting point 1830 ~ 1850 , boiling point of 2500 ~ 3000 . 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.
