· JVASP-50829· CaY2O4

CaY2O4 is a calcium yttrium oxide ceramic compound belonging to the rare-earth oxide family, combining alkaline-earth and lanthanide chemistry. This material is primarily studied for high-temperature applications and optical/photonic systems where rare-earth doping and thermal stability are required. It offers potential advantages in refractory coatings, phosphor hosts for lighting, and as a matrix material in composite systems where the combination of calcium and yttrium oxides provides enhanced thermal conductivity or luminescent properties compared to single-component alternatives.

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.
