ceramic· JVASP-58496· AlCr2O4
Chromium aluminate (AlCr₂O₄) is a spinel-structured ceramic compound combining aluminum and chromium oxides, valued for its thermal stability and resistance to chemical attack at high temperatures. It is primarily used in refractory applications, thermal barrier coatings, and high-temperature structural components where resistance to oxidation and thermal cycling is critical. Engineers select this material over conventional alumina or chromia refractories when superior corrosion resistance to molten salts and slag, combined with moderate thermal conductivity control, offers a design advantage in extreme-service environments.

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.
