ErGeAu

ErGeAu is an intermetallic compound combining erbium, germanium, and gold—a rare ternary metal system primarily of research interest rather than established commercial production. This material belongs to the class of precious-metal intermetallics and is investigated for its potential in high-performance applications requiring combinations of thermal stability, electrical properties, or specialized mechanical behavior. Limited industrial deployment exists; ErGeAu and similar ternary systems are explored in materials science to understand phase stability, electronic structure, and potential use in niche applications such as thermoelectrics, electronic contacts, or advanced aerospace components where cost is secondary to performance.
