· JVASP-27665· Ca2Cr3O8

Ca₂Cr₃O₈ is a mixed-valent calcium chromium oxide ceramic compound belonging to the family of chromium-based oxides used in specialized industrial applications. This material is primarily encountered in refractory and pigment applications where chromium-containing ceramics provide thermal stability and chemical resistance at elevated temperatures. Its use is relatively specialized compared to common structural ceramics, making it of interest to engineers working on high-temperature oxidation resistance, corrosion-resistant coatings, or pigmentation in demanding thermal 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.
