· JVASP-49962· KHoO2

KHoO2 is a potassium holmium oxide ceramic compound belonging to the rare-earth oxide family. This material is primarily encountered in research and specialty applications rather than established industrial production, where it serves roles requiring rare-earth chemistry combined with ceramic stability. Engineers would consider KHoO2 in advanced applications exploiting holmium's unique optical, magnetic, or nuclear properties—such as laser host materials, neutron absorption, or high-temperature refractory systems—where the potassium-holmium oxide phase provides thermal stability and chemical inertness unavailable in simple oxides.
