· JVASP-142805· Al9CrB2O18

Al9CrB2O18 is an advanced oxide ceramic compound combining aluminum, chromium, and boron oxides, representing a quaternary ceramic system designed for high-temperature and wear-resistant applications. This material belongs to the family of complex oxide ceramics and appears to be primarily explored in research and specialized industrial contexts where conventional alumina or chromia-based ceramics fall short. The chromium and boron oxide additions likely enhance hardness, oxidation resistance, and thermal stability compared to single-phase alternatives, making it relevant for extreme environments requiring both chemical and mechanical durability.

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.
