· JVASP-21643· ErVB4

ErVB4 is an erbium vanadium boride intermetallic compound, part of the rare-earth transition metal boride family. This is a research-phase material studied for its potential in high-temperature structural applications and advanced ceramics, where rare-earth borides are investigated for refractory properties and oxidation resistance. Limited commercial deployment exists; its engineering relevance depends on specific high-temperature or wear-critical requirements where boride hardness and thermal stability provide advantages over conventional alloys.

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.
