Product Description
chromium oxide green; Chromic Oxide; Chromium (III) Oxide
High Purity 99% Chrome Oxide Green
Our chrome oxide green is produced from high quality chromic acid flakes, with very low impurities as well as very low hexavalent chromium content which can reach to 5ppm max. It 's particle size is well distributed.
Chrome oxide green has strong tinting strength, hardness and melting pointing which makes it idea material for pigment, abrasive product and fire resistant product.

How is the product manufactured?
Calcium-free oxidative roasting process is the technological used to produce chromic salts for environmental protection. basicaly there are 2 methods for the production of chrome oxide green. One is Reduction by ammonium chloride reduction of sodium bichromate, thermal decomposition method. Both get high purity chrome oxide green but with different color shade.
How many types of chromium oxide can be produced?
We can provide chromium oxide for different applications
1. Pigment grade chrome oxide green
2. Refractory grade chrome oxide green
3. Metallurgic grade chrome oxide green
4. Polishing grade chrome oxide green
How is the hexavalent chromium Cr6+ level in product?
Normally Cr6+ content in chrome oxide green is less than 150ppm.
It can also be control the zero level according to customer requirement.
