· Er2 B4 C1

Er₂B₄C is a ternary ceramic compound combining erbium, boron, and carbon, belonging to the family of rare-earth boron carbides. This material is primarily investigated in research contexts for high-temperature structural applications and advanced ceramic composites, where the rare-earth element provides oxidation resistance and the boron-carbon framework contributes hardness and thermal stability. Er₂B₄C and related rare-earth boron carbides are notable alternatives to conventional refractory ceramics in demanding environments because they combine potential for improved fracture toughness with retention of strength at elevated temperatures, though industrial adoption remains limited compared to established materials like silicon carbide or alumina.

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.
