TbH3O3

TbH3O3 is a terbium-based oxyhydride ceramic compound combining rare-earth terbium with hydrogen and oxygen in a fixed stoichiometry. This material is primarily of research interest rather than established in production engineering, representing an emerging class of functional ceramics that exploit rare-earth properties for potential use in advanced applications requiring high stiffness and chemical stability. The compound belongs to the rare-earth oxyhydride family, which shows promise in catalysis, energy storage, and specialized optical or magnetic applications where rare-earth elements provide unique functionality.
