Titanium Dioxide Granules（TiO2 Granules）

Physical and chemical properties

Titanium Dioxide is a dye and pigment. Relative molecular mass: 79.8658.CAS registration number: 13463-.67-7. Density: 4.26g/cm3 Soft, odorless and tasteless white powder with strong hiding power and tinting power, melting point 1560～1580℃. Insoluble in water, dilute inorganic acid, organic solvent, oil, slightly soluble in alkali, soluble in concentrated sulfuric acid.

It turns yellow when heated and turns white when cooled. Rutile type (R type) density 4.26g/cm3, refractive index 2.72. R-type titanium dioxide has the characteristics of good weather resistance, water resistance and not easy to yellow, but the whiteness is slightly worse. Anatase type (A type) has a density of 3.84g/cm3 and a refractive index of 2.55. A-type titanium dioxide has poor light resistance and weathering resistance, but has good whiteness.

Application

Used in paint, ink, plastic, rubber, paper, chemical fiber and other industries; used in welding rods, refining titanium and manufacturing titanium dioxide. Titanium dioxide (nanoscale) is widely used in white inorganic pigments such as functional ceramics, catalysts, cosmetics and photosensitive materials. It has the strongest tinting strength among white pigments, with excellent hiding power and color fastness, and is suitable for opaque white products. The rutile type is especially suitable for plastic products for outdoor use, which can endow the products with good light stability. Anatase type is mainly used for indoor use products, but with a slight blue light, high whiteness, high hiding power, strong tinting power and good dispersion. Titanium dioxide is widely used as a pigment for paint, paper, rubber, plastic, enamel, glass, cosmetics, ink, watercolor and oil paint, and can also be used in metallurgy, radio, ceramics, and welding rods.
