the following example is for you reference.


Main Advantages:

Chrome Oxide Green(COG) is also called Chromium oxide, molecular weight is 151.99, in hexagonal system, light green or dark green powder.

COG's bulk density is 5.21g/cm', melting point is 2265 'C, boiling point is 3654 C.

COG is insoluble in water,acid or organic solvent, but can be slightly soluble in concentrated sodium hydroxide solution, soluble in hot sodium bromate solution, hot concentrated perchloric acid solution or boiling sulphur& phosphorus mixed acid.

COG is used in magnetic Material, electronic material, and special hard alloy industry.

Product superiority: Special tchnique production with nigh purity; low inpurity, superfine powder.
