Used as a green pigment in ceramics, glass, and paints due to its stability at high temperatures and resistance to UV light. Commonly applied in coloring cement, concrete, and architectural products for decorative finishes. Employed in the production of refractory materials because of its high melting point and chemical inertness. Also utilized as a polishing compound for metals and optical surfaces, where it provides a fine, scratch-free finish. Finds use in some catalysts and in the metallurgical industry for chromium-based alloy production.
