Used as a pigment in paints, inks, and plastics due to its stable green color and resistance to light and weathering. Commonly applied in architectural coatings and industrial finishes where durability is required. Also utilized in polishing compounds for glass, metals, and optical materials because of its moderate abrasiveness. Finds use in the production of refractory materials and ceramics for high-temperature applications. Occasionally employed in the synthesis of other chromium compounds where a hydrated oxide precursor is needed.
