· HoAlO3

Holmium aluminum oxide (HoAlO₃) is a rare-earth ceramic compound combining holmium, a lanthanide element, with aluminum oxide in a defined stoichiometric ratio. This material is primarily of research and specialized industrial interest rather than a commodity ceramic, valued for its unique combination of rare-earth properties and structural stability. HoAlO₃ appears in advanced applications requiring rare-earth functionality—such as optical devices, phosphors, high-temperature ceramics, and potentially in emerging fields like solid-state lasers or neutron absorbers—where the holmium dopant or host lattice properties provide performance advantages over conventional alumina or other rare-earth ceramics.
