Uses
Copper chromite black spinel has a blackness second only to carbon black, and possesses high temperature and weather resistance, making it widely used in various high-end coatings, high-temperature plastics, building materials, glass, ceramics, and other fields. In the coatings industry, it is suitable for non-stick cookware coatings, general industrial coatings, fluorocarbon coatings, coil coatings, powder coatings, automotive coatings, architectural and exterior wall coatings, engineering machinery coatings, aerospace and marine coatings, military camouflage coatings, road marking coatings, rock mural coatings, painting coatings, oil-based and water-based coatings, sun-resistant, weather-resistant, and UV-resistant coatings, and high-temperature coatings. Liquid-phase synthesized copper chromate black can also be used in engineering plastics, specialty plastics, masterbatches, and ordinary plastics, as well as in colored inks, colored glass, daily-use enamel, building ceramics (overglaze and underglaze), and colored sand and gravel.
Definition
Copper chromite black spinel is an inorganic pigment that is the reaction product of high temperature calcination in which copper (II) oxide and chromium (III) oxide in varying amounts are homogeneously and ionically interdiffused to form a crystalline matrix of spinel. Its composition may include any one or a combination of the modifiers Fe2O3 and MnO.
