ceramic

· ErAlO3

ErAlO3 is a rare-earth aluminate ceramic compound combining erbium oxide with alumina in a perovskite or mixed-phase crystal structure. This material is primarily investigated in research and specialized applications where its thermal stability, optical properties, and refractory characteristics are advantageous—particularly in high-temperature environments and photonic device contexts where rare-earth dopants or hosts are critical.

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.
