· JVASP-44510· Cr3O4

Chromium sesquioxide (Cr₃O₄) is a mixed-valence ceramic oxide combining chromium in both +2 and +3 oxidation states, forming a spinel-related structure. It appears in high-temperature oxidation protection systems and specialized refractory applications where chromium's strong oxide stability is leveraged, though it is less common than pure Cr₂O₃ in industrial practice. This material is notable for its potential in thermal barrier coatings and corrosion resistance at elevated temperatures, particularly in research contexts exploring alternative chromium ceramic phases for specific high-temperature 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.
