· ErB2

ErB₂ is an erbium diboride ceramic compound belonging to the hexaboride family of refractory materials. This material is primarily studied in advanced research contexts for applications requiring extreme hardness, thermal stability, and chemical resistance at high temperatures. ErB₂ and related rare-earth borides are candidates for cutting tool inserts, wear-resistant coatings, and specialized refractory applications where conventional ceramics fall short, though industrial adoption remains limited compared to established alternatives like tungsten 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.
