· JVASP-123240· Er3Re

Er3Re is a ceramic intermetallic compound composed of erbium and rhenium, belonging to the rare-earth refractory ceramics family. This material is primarily of research interest for high-temperature structural applications, where its combination of rare-earth and refractory metal components offers potential for extreme thermal environments and specialized aerospace or nuclear contexts. Er3Re and related erbium-rhenium phases are investigated as candidate materials for advanced thermal protection systems and high-temperature oxidation-resistant coatings, though industrial adoption remains limited compared to established superalloys and traditional refractory 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.
