Chromium(III) oxide

Chromium(III) oxide (Cr₂O₃) is a chemical compound made of chromium and oxygen. It appears as a stable, greenish-black powder that is resistant to heat and corrosion. This material is often used as a pigment in paints, ceramics, and inks due to its vibrant color and durability. Additionally, it serves as a refractory material in high-temperature industrial applications and as a catalyst in various chemical reactions. Chromium(III) oxide's stability, color, and toughness make it valuable in both aesthetic and industrial contexts.
