Chrome green, also known as enamel chrome green, is mainly composed of chromium trioxide (Cr2O3). Like other high temperature resistant inorganic pigments, it can be used for coloring enamel, ceramics, rubber, glass, etc., and can also be used in the manufacture of high temperature resistant coatings or high temperature paints.

Chrome green generally presents olive green, and its color is close to the chlorophyll of plants. It can be used for camouflage paint. It can make it difficult to distinguish in infrared photography. In addition, it is also widely used in metallurgy, making refractory materials, grinding powder, and chrome green can also be used as organic synthesis catalyst.

Chromium oxide green is a very good green pigment, it has excellent high temperature resistance, can withstand up to 1000 ℃ without discoloration, very outstanding weather resistance, extremely stable to light, atmosphere and corrosive gases (SO2, H2S4, etc.), acid and Alkali resistance is also very good, and non-toxic. It is both a pigment and the main raw material for other pigments such as melanin.

There are three industrial production methods for chromium oxide green: high temperature calcination, reduction of chromic anhydride, and dehydration and calcination of chromium hydroxide.
