Ho2 Hg6

Ho₂Hg₆ is an intermetallic compound combining holmium (a rare-earth element) with mercury, classified as a semiconductor material. This compound belongs to the rare-earth mercury intermetallic family and is primarily of research interest rather than established industrial production. Ho₂Hg₆ and related rare-earth mercury phases are studied for potential low-temperature physics applications, including superconductivity research and quantum material investigations, though practical engineering adoption remains limited due to mercury's toxicity, volatility, and regulatory constraints.
