· JVASP-38804· Ho2AlOs

Ho2AlOs is an intermetallic compound combining holmium (a rare-earth element) with aluminum and oxygen, belonging to the family of rare-earth aluminate ceramics. This material is primarily of research and development interest rather than established industrial production, investigated for high-temperature structural applications and potential functional properties arising from holmium's magnetic characteristics. The combination of a rare-earth metal with aluminum suggests potential use in advanced ceramics where thermal stability, wear resistance, or magnetic functionality at elevated temperatures could provide advantages over conventional alumina or nickel-based alloys.
