Inorganic pigment Anatase titanium dioxide

1.

Anatase Titanium Dioxide, chemical name titanium dioxide, molecular formula Ti02, molecular weight 79.88. White powder, relative density 3.84. The melting point is 1560°C. Water absorption 0.02%. High temperature (>700°C) heating transforms into rutile crystals. The melting point is about 1800°C. The refractive index is 2.55. The average particle size is 0.15~0.23um. Mohs hardness 5-6. Stable chemical properties, light resistance, heat resistance, dilute acid resistance, dilute alkali resistance. It has strong tinting power (hiding power) and dispersing power. The durability is not as good as rutile titanium dioxide, the light resistance is poor, and the adhesive layer is easy to pulverize after being combined with resin. When the temperature is higher than 400℃, it is obviously yellow. Insoluble in water, organic acids and inorganic acids, soluble in concentrated sulfuric acid, alkali and hydrofluoric acid. Non-toxic, the maximum allowable concentration in the air is 10mg/m3.
