· JVASP-20811· ErB4

ErB4 is an erbium boride ceramic compound belonging to the rare-earth boride family, characterized by high hardness and thermal stability. This material is primarily of research and development interest for extreme-temperature applications and wear-resistant coatings, where its hardness and refractory properties offer potential advantages over conventional ceramics, though industrial adoption remains limited compared to established boride systems like TiB2.

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.
