· JVASP-22885· Mg3BeAl8O16

Mg3BeAl8O16 is a complex ternary oxide ceramic combining magnesium, beryllium, and aluminum in a single-phase crystal structure. This material belongs to the spinel or spinel-related ceramic family and is primarily encountered in research and advanced materials development rather than widespread industrial production. Its combination of light elements (Mg, Be, Al) with ceramic hardness makes it of interest for applications requiring low density coupled with structural rigidity, though its beryllium content presents significant health and processing challenges that limit adoption compared to conventional ceramics.

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.
