Stability
1. Boil for a long time to dissolve in concentrated sulfuric acid and hydrofluoric acid. React with molten sodium hydroxide to form titanate. At high temperatures, it can be reduced to low valent titanium compounds by hydrogen, carbon, metallic sodium, etc., and reacts with carbon disulfide to generate titanium disulfide. The refractive index of titanium dioxide is the highest among white pigments, with a rutile type of 8.70 and an anatase type of 2-55. Due to the fact that both anatase and plate titanium dioxide transform into rutile type at high temperatures, the melting and boiling points of plate titanium and anatase titanium dioxide do not actually exist. Only rutile type titanium dioxide has a melting point and boiling point. The melting point of rutile type titanium dioxide is 1850 ℃, the melting point in air is (1830 ± 15) ℃, and the melting point in oxygen rich is 1879 ℃. The melting point is related to the purity of titanium dioxide. The boiling point of rutile type titanium dioxide is (3200 ± 300) K, and at this high temperature, titanium dioxide is slightly volatile.
