Cr2O3

Cr₂O₃, or chromium(III) oxide, is a dark green, hard ceramic material made from chromium and oxygen. It is commonly used as a pigment in paints, inks, and coloring agents due to its vibrant, stable green color. Additionally, Cr₂O₃ has high corrosion resistance and is employed as a protective coating for metal objects, enhancing their durability. It is also utilized in the manufacturing of refractory materials and electronic components. Its stability at high temperatures and resistance to oxidation make Cr₂O₃ valuable in various industrial applications.
