Er2V2O7

Er2V2O7 is an erbium vanadate ceramic compound belonging to the rare-earth vanadate family, characterized by a pyrochlore or related crystal structure containing erbium (a lanthanide) and vanadium oxide units. This material is primarily investigated in research contexts for high-temperature applications and functional ceramics, where rare-earth vanadates are valued for their thermal stability, chemical inertness, and potential use in thermal barrier coatings, nuclear waste immobilization, and specialty refractory applications. Engineers consider rare-earth vanadates when conventional oxides prove inadequate in extreme thermal or chemical environments, though Er2V2O7 remains largely experimental outside dedicated research programs.
