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, the other is Chromic anhydride 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
