· JVASP-14752· ErGe3

ErGe3 is an intermetallic ceramic compound combining erbium (Er) and germanium (Ge) in a 1:3 stoichiometric ratio. This material belongs to the rare-earth germanide family and is primarily encountered in research and materials development contexts rather than established industrial production, where it is investigated for potential applications in thermoelectric devices, high-temperature structural components, and specialized electronic or photonic systems. The incorporation of erbium, a lanthanide element, confers potential for tuned electronic band structure and thermal properties, making it of interest to researchers exploring alternatives to conventional ceramics in demanding thermal or electrical environments.
