ErVB4
metal· 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.
