1)Brief introduction:
Chromium Oxide Green powderis light green to dark green. Density: 5.21. Melting point: 2266 degrees. Boiling point: 4000 degrees. With metallic luster, magnetism, covering power is strong, high temperature resistant, weather resistant, insoluble in water, soluble in acid, to be stable in the atmosphere for the average concentration of acid and alkali and sulfur dioxide gas no effect, good paint quality and fastness.
2)Function of Chromium Oxide Green powder:
1. IT is used for enamel, color glass industry, especially for the production of ceramic pigment, bright bright color products.
2. IT is used for heat resistance coating, fluorocarbon coatings, outdoor high resistance to wait coating; Outdoor plastic products, plastic doors and Windows profiles, color masterbatch, etc.
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.

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, the other is Chromic anhydride thermal decomposition method. Both get high purity chrome oxide green but with different color shade.
1.Low Cr6+ 5PPM
2.Nearly 1500 tons per month and deliver on time
3.Fully meet EU standard and SGS TEST
