· JVASP-50867· LuHO2

LuHO2 is a lutetium-based hydroxide ceramic compound that belongs to the rare-earth oxide ceramic family. This material is primarily of research and development interest rather than established commercial production, with potential applications in high-temperature structural ceramics, optical materials, and specialized refractory systems where rare-earth oxides offer superior thermal stability and chemical inertness. The incorporation of lutetium—the densest lanthanide element—makes this compound notable for applications requiring high density combined with ceramic thermal and chemical resistance.
