· JVASP-49856· K2Be2O3

K2Be2O3 is a beryllium-containing oxide ceramic compound that combines potassium and beryllium oxides in a stable crystalline structure. This material is primarily of research and specialized industrial interest rather than a commodity ceramic, valued for applications requiring the unique combination of beryllium's low density and high thermal stability with oxide ceramic properties. Its primary appeal lies in high-temperature environments and advanced optical or refractory applications where beryllium's exceptional thermal conductivity and low neutron absorption cross-section are beneficial, though production and handling are constrained by beryllium toxicity considerations and the material's limited commercial availability.

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.
