· ReYO3

ReYO3 is a rare-earth yttrium oxide ceramic compound, part of the rare-earth oxide family that exhibits high thermal stability and refractory properties. While specific industrial production data is limited, rare-earth oxide ceramics like this composition are investigated for high-temperature structural applications, optical devices, and as constituent phases in advanced ceramic composites. The yttrium-oxygen system is particularly valued in environments requiring chemical inertness and thermal shock resistance, making it relevant to aerospace, electronic substrates, and specialty thermal barrier applications.

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.
