Ho2Al3Si2
metal· JVASP-15189· Ho2Al3Si2
Ho₂Al₃Si₂ is an intermetallic compound combining holmium (a rare-earth element) with aluminum and silicon, forming a brittle metallic phase rather than a traditional alloy. This is a research-stage material studied primarily for understanding rare-earth intermetallic systems and their potential in high-temperature structural applications, though it has not achieved widespread commercial use. The incorporation of holmium—known for magnetic and neutron-absorption properties—may offer specialized advantages in nuclear or magnetically-sensitive environments where conventional aluminum-silicon alloys fall short.
