HoH₂ is a hydride ceramic compound based on holmium, belonging to the rare-earth metal hydride family. This material exhibits the crystalline structure and mechanical properties typical of intermetallic hydrides, making it of interest in research contexts for hydrogen storage, advanced ceramics, and high-temperature applications. While not yet widely commercialized, holmium hydrides represent an emerging material class being investigated for energy storage solutions and specialized refractory applications where rare-earth elements provide enhanced thermal and chemical stability.
