Chrome Oxide Green

  /> </div>
<div class=

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.

Applications:                                                                                                         - use as an ingredient in the refractories and brake linings
- as a raw material for the manufacture of chromium metal
- as a raw material for production of mixed metal oxides in the ceramic industry
- as green pigment for coloring building materials, plastics and also as a refractory

Packaging: 
- Available in 1000 kg bags or 40 X 25 kg bags, palletized

Basic Chromium Sulphate
