Chromium oxide green，chrome oxide green

Green crystal powder bright shade; better covering strength than chrome oxide green common type; good pigment property after purification and a wide range of application

Chromium oxide green, also known as chromium sesquioxide or chromia, is one of four oxides of chromium, chemical formula Cr2O3. It is commonly called chrome green when used as a pigment; however it was referred to as viridian when it was first discovered.
Hydrated chromium oxide is permanent, but chromium oxide is more stable and is one of the most permanent pigments an artist uses. It will not react with hydrochloric acid or with sodium hydroxide.
Chromium oxide green absorbs a small amount of oil (26 g oil per 100 g of pigment).

High purity chrome oxide green is mAInly used as pigment for high class porcelain glaze making, printing ink for paper money, pigment for cosmetics etc.
