· JVASP-131470· ErB11

ErB11 is a rare-earth boride ceramic compound combining erbium with boron in an 11:1 stoichiometric ratio. This material belongs to the family of rare-earth hexaborides and boride ceramics, which are of significant research interest for high-temperature and extreme-environment applications. ErB11 is primarily investigated in advanced materials research contexts rather than widespread industrial production, with potential applications leveraging the inherent hardness, refractory nature, and thermal stability characteristic of boride ceramics.

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.
