Chrome Oxide Green

 
 

Light to dark green or bright green, fine crystalline solid. CAS No.: 1308-38-9

Kroxide is Chromium(III) Oxide inorganic compound of the formula Cr2O3. It is one of the principal oxides of chromium and is used as a pigment. Chrome green can be used to refer to a mixture of chrome yellow (Lead Chromate) and prussian blue (Ferrocyanate).

Chrome oxide green is used in manufacturing of linoleum, ceramic glazes, industrial coatings, frits, colored glass, plastics, roofing tiles, stainless steel electrodes, paints, inks and glasses. In addition to this it is also used in the production of aerospace super-alloys and refractory bricks for glass and fiberglass industry.
