Description
Chrome Oxide Green(COG) is also called chromium oxide, molecular weight is 151.99, in hexagonal system, light green or dark green powder.
Relative density is 5.21g/cm3, refractive index is 2.5(good hiding power). melting point is 2265ºC, boiling point is 3654ºC.
Normally has metallic luster, magnetic properties, great hiding power, high temperature resistance, sunlight resistance, and insoluble in water or acid. Stable in air, has no influence to regular acid, alkali , hydrogen sulfide and other gases.
COG has excellent pigment quality and sturdiness, best hiding power, color saturation, occupies an important position in the fields of inorganic pigment.
Widely used in ceramic, enamel, coating, ink, paint, green floor, green glass, and other fields.
