Chrome Oxide Green
Molecuar Formula: Cr2O3
Molecuar Weight: 151.99
Character: It is cubic crystal system or amorphous powder,and specilized production all kinds of model number chromium oxide green .olive Green, which has metallic luster. Its gravity is 5.21,melting point is 2,266±25℃ and boiling point is 4,000℃.It can not dissolve in water and acidic solution, but an dissolve in the solution of alkali metallic bromate. It is very stable to light, atmosphere, high temperature and corrosive gas (SO2, H2S etc). It has high covering power and magnetism.
Usage: It is mainly used in colouring of ceramics and enamel and coloured drawing or pattern, making green polishing compound, imitation leather and catalyst for organic synthesis, as well as refractory materials, paint, paint ,printing ink, smelting metal chrome and chrome carbide and making ruby.
