· Be2 O2

Beryllium oxide (BeO) is a high-performance ceramic compound combining beryllium metal with oxygen, belonging to the family of refractory oxides. While BeO itself is a well-established technical ceramic, the notation Be₂O₂ may represent a non-stoichiometric or research-phase variant; classical beryllium oxide exhibits exceptional thermal conductivity and electrical insulativity, making it valuable in demanding thermal management and electronics applications despite toxicity concerns that limit its use.

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.
