Ba2CrO4
ceramicBarium chromate (Ba₂CrO₄) is an inorganic ceramic compound composed of barium and chromate ions, belonging to the class of heavy metal oxyanion ceramics. It is primarily used in specialized coatings, pigments, and corrosion-inhibiting applications where its chemical stability and high refractive index are advantageous. The material is notable for its use as an anti-corrosion pigment in primers and protective coatings for steel structures, and as a bright yellow pigment in industrial paints, though its application is increasingly restricted in some regions due to chromium toxicity concerns; engineers typically evaluate it against alternative non-toxic chromate compounds or organic pigments depending on regulatory environment and performance requirements.
