· JVASP-143969· Ba2CrO4

Barium 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.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
