· JVASP-39270· Lu2BeOs

Lu₂BeO₅ is a rare-earth beryllium oxide ceramic compound combining lutetium (the densest lanthanide) with beryllium oxide, forming a complex ternary oxide phase. This is a specialized research material rather than a commercial product; it belongs to the family of rare-earth ceramics and refractory compounds of interest for extreme-environment applications where high density, thermal stability, and chemical resistance are required simultaneously.

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.
