· Be2O3

Be₂O₃ (beryllium oxide) is a high-performance ceramic compound that combines beryllium's lightweight character with oxygen's oxidation resistance, forming a refractory ceramic material. It is used in specialized aerospace, nuclear, and high-temperature electronics applications where extreme thermal stability, low density, and excellent thermal conductivity are required—particularly in thermal management components, neutron moderators, and substrates in demanding environments. Be₂O₃ is notable for its ability to operate at very high temperatures while maintaining structural integrity, though its use requires careful handling due to beryllium toxicity and cost considerations relative to conventional ceramics like alumina.

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.
