· JVASP-73427· Be2ReRu

Be₂ReRu is an experimental intermetallic ceramic compound combining beryllium, rhenium, and ruthenium—a high-entropy metallic system rather than a traditional oxide or carbide ceramic. This material belongs to the class of advanced refractory intermetallics, designed to explore extreme-condition performance where conventional ceramics or superalloys reach their limits. Be₂ReRu is primarily a research-phase material; its combination of low-density beryllium with ultra-refractory transition metals (Re, Ru) targets next-generation applications demanding exceptional high-temperature strength, thermal stability, and oxidation resistance, though such ternary systems remain largely in laboratory development with limited commercial deployment.

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.
