· JVASP-116114· AlCrO2

Chromium aluminate (AlCrO₂) is a mixed oxide ceramic compound combining aluminum and chromium oxides, offering potential for high-temperature and corrosive-environment applications. This material is primarily of research and specialized industrial interest, valued in refractory systems, catalytic supports, and protective coatings where thermal stability and chemical resistance are critical. Engineers would select it over conventional aluminas or chromias when both thermal shock resistance and oxidation resistance are needed simultaneously, or when the mixed-oxide microstructure provides catalytic benefits.

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.
