Product Description
Chemicals Name:Copper Chromite Black Spinel
CAS: 68186-91-4
Index: Pigment Black 28; C.I.: 77428
This Product is generated through the solid-phase reaction of various metal oxides at high temperatures, which is environmentally friendly, non-toxic, and weather-resistant inorganic pigment. The pure crystal structure is formed through the impurity removal process. The pigment is a pure crystal which without the metal properties and oxidized properties of the metallic oxide in the raw materials are more stable physical and chemical properties.
