Chromium(III) oxide is a Inorganic compound with chemical formula of Cr2O3. It is a green crystalline powder, insoluble in water, acid and alkali solutions, but soluble in hot alkali metal Bromate solution. It is mainly used for coloring ceramics and enamel, and can also be used as analytical reagent and catalyst.

Light green to dark green small hexagonal crystals. When hot, it turns brown, but when cold, it still turns green. The crystal is extremely hard. Extremely stable, even when hydrogen gas is introduced under red heat, there is no change. Soluble in heated Potassium bromate solution, slightly soluble in acids and bases, almost insoluble in water, ethanol and acetone.

On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization (WHO) was preliminarily sorted out for reference, and chromium (III) compounds were included in the list of three types of carcinogens.

Hexagonal crystal family or amorphous dark green powder. Has a metallic luster. 

Cubic crystal system or amorphous green powder. There are usually two shades: light olive green and deep olive green. Has a metallic color. Relative Density5.21. Melting_ Point 2266 ℃. Boiling_ Point 4000 ℃. It has excellent heat resistance, can withstand a temperature of 1000 ℃ without discoloration, and has excellent acid and alkali resistance. Insoluble in water, insoluble in acid, soluble in hot alkali metal Bromate solution. Extremely stable to corrosive gases such as light, atmosphere, and sulfur dioxide and hydrogen sulfide. It has a high hiding power, but its coloring power is not as strong as phthalocyanine green. The color tone is not bright enough, the particle size is hard, and the glossiness of the paint is slightly poor. Having magnetism. Toxic.

Main purpose

Mainly used in special steel smelting tapping holes, sliding plate openings, and large incinerators, it can be used for coloring ceramics and enamel, coloring rubber, preparing high-temperature resistant coatings, art pigments, and preparing ink for printing banknotes and securities. The color of chromium oxide green is similar to that of plant chlorophyll and can be used as camouflage paint, making it difficult to distinguish in infrared photography. It is also widely used in metallurgy, making refractory materials, and grinding powders. It can also be used as an organic synthesis catalyst and is an advanced green pigment.
