Anatase titanium dioxide, chemical name titanium dioxide, molecular formula TiO2, molecular weight 79.88. White powder, relative density 3.84. Melting point 1560 ℃. Water absorption 0.02%. High temperature (>700 ℃) heating into rutile crystal. The melting point is about 1800°C. Refractive index 2.55. The average particle size is 0.15~0.23um. Mohs hardness of 5 to 6. Stable chemical properties, light resistance, heat resistance, dilute acid resistance, dilute alkali resistance. It has strong tinting power (covering power) and dispersing power. The durability is not as good as that of rutile titanium dioxide, the light resistance is poor, and the adhesive layer is easy to powder after mixing with the resin. The temperature is higher than 400 ℃ obviously yellow. Insoluble in water, organic acid and inorganic acid, soluble in concentrated sulfuric acid, alkali and hydrofluoric acid. Non-toxic, the highest allowable concentration in the air is 10mg/m3.
