ErRh2

ErRh2 is an intermetallic compound combining erbium (a rare-earth element) with rhodium in a 1:2 stoichiometric ratio, forming a ceramic-class material with high density and potential for specialized high-temperature applications. This material represents a research-phase intermetallic rather than a widely commercialized engineering ceramic; the ErRh2 system is primarily studied for its thermodynamic stability, magnetic properties, and potential use in advanced alloy development and materials science research rather than established industrial production. Its notable density and rare-earth character make it relevant to exploratory work in high-performance alloys, catalytic systems, or specialized aerospace/materials research contexts where rare-earth intermetallics are investigated.
