· JVASP-61835· ErB2Ru

ErB₂Ru is a ternary ceramic compound combining erbium, boron, and ruthenium—a research-phase material belonging to the family of hexaborides and transition-metal borides. This dense ceramic exhibits characteristics typical of high-melting-point boride systems and is primarily investigated for extreme-environment applications where conventional ceramics reach their thermal or chemical limits. The material remains largely experimental, with development focused on aerospace, nuclear, and high-temperature structural applications where its refractory properties and metallic-ceramic hybrid behavior may offer advantages over single-phase borides or traditional superalloys.

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.
