BaCr4O8
ceramic· JVASP-57886· BaCr4O8
Barium chromate (BaCr₄O₈) is an inorganic ceramic compound belonging to the chromate family, typically used as a pigment and corrosion inhibitor in industrial coatings and surface treatments. It finds application in aerospace, automotive, and marine industries where corrosion protection of aluminum and steel substrates is critical, though environmental and health regulations have restricted its use in many regions due to hexavalent chromium content. Engineers may select this material for legacy systems or specialized applications where its strong inhibitive properties justify compliance overhead, though safer chromate alternatives are increasingly preferred.

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.
