· JVASP-137017· YAlO2

YAlO₂ (yttrium aluminum oxide) is an advanced ceramic compound belonging to the family of rare-earth aluminate ceramics. It is primarily of research and specialized industrial interest, valued for its thermal stability, chemical inertness, and potential as a refractory material or high-temperature component. Applications include high-temperature structural ceramics, thermal barrier coatings, and specialized optical or electronic components where rare-earth doping and phase stability are advantageous compared to conventional aluminas.

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.
