· JVASP-39038· SmY3

SmY3 is a rare-earth oxide ceramic composed of samarium and yttrium, belonging to the family of rare-earth sesquioxides used in high-performance structural and functional applications. This material is primarily employed in thermal barrier coatings for aerospace engines, solid oxide fuel cells, and scintillation devices, where its combination of thermal stability and optical properties is valued. SmY3 represents a specialized engineering ceramic chosen for environments requiring both chemical inertness and controlled thermal conductivity, offering advantages over single-component rare-earth oxides in stabilizing crystal phases and improving mechanical reliability at elevated temperatures.

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.
