Chromium oxide (Cr₂O₃) is an inorganic chromium compound belonging to the technically important metal oxides. This characteristic green powder features high thermal and chemical resistance and is used in various industrial and technical applications.
One of the best-known applications of chromium oxide is its use as a green pigment. Thanks to its high color stability and good resistance to high temperatures, light, and atmospheric influences, Cr₂O₃ is suitable for the production of coatings, paints, and ceramic materials.
Due to its high hardness and wear resistance, chromium oxide is also used for the production of technical ceramics, refractory materials, and protective coatings. In surface treatment technologies, it can be a component of wear-resistant and heat-resistant coatings.
