· JVASP-15392· HoCuSi

HoCuSi is a ternary intermetallic compound combining holmium, copper, and silicon—a rare-earth metal system primarily of research and development interest rather than established industrial production. This material family is explored for potential applications in high-temperature structural applications, magnetic systems, and advanced alloys where rare-earth strengthening or specialized electronic properties may offer advantages over conventional alternatives.
