Physical property data
White powder.
Soft, odorless and tasteless white powder with strong hiding power and coloring power, and its melting point is 1560 ~ 1580℃. Insoluble in water, dilute inorganic acid, organic solvent and oil, slightly soluble in alkali and soluble in concentrated sulfuric acid. It turns yellow when heated, and turns white when cooled. Rutile (R type) has a density of 4.26g/cm3 and a refractive index of 2.72. R-type titanium dioxide has good weather resistance, water resistance and is not easy to turn yellow, but its whiteness is slightly poor. The anatase type (type A) has a density of 3.84g/cm3 and a refractive index of 2.55. Type A titanium dioxide has poor light resistance and weathering resistance, but its whiteness is good. In recent years, it has been found that nano-sized ultra-fine titanium dioxide (usually 10 ~ 50 nm) has semiconductor properties, high stability, high transparency, high activity and high dispersibility, and has no toxicity or color effect.
