BaCrO4

Barium chromate (BaCrO₄) is an inorganic ceramic compound that forms bright yellow crystals and is primarily valued for its chemical stability and corrosion resistance at elevated temperatures. It is used as a pigment in coatings and paints, as a corrosion inhibitor in primers and protective finishes, and in specialized ceramic and refractory applications where yellow coloration and chemical inertness are required. Engineers select barium chromate where environmental durability and resistance to chemical attack are critical, though regulatory restrictions on hexavalent chromium compounds have driven increased consideration of alternative pigments in some regions.
