· JVASP-153454· ErB12

ErB12 is a rare-earth hexaboride ceramic compound belonging to the boride family, where erbium combines with boron in a 1:12 stoichiometry to form a hard, refractory phase. This material is primarily of research and specialized industrial interest, valued for its exceptional hardness, high melting point, and chemical stability at extreme temperatures, making it a candidate for ultra-hard coatings, wear-resistant applications, and high-temperature structural components where conventional ceramics reach their limits.

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.
