· BaH2

Barium hydride (BaH₂) is an ionic ceramic compound belonging to the metal hydride family, characterized by strong Ba–H bonding in a crystal lattice structure. While primarily of research and development interest rather than established industrial production, BaH₂ is investigated for hydrogen storage applications, neutron shielding, and as a precursor in advanced materials synthesis due to its high hydrogen content and thermal stability. The material represents an emerging class within functional ceramics where hydrogen density and chemical reactivity are critical performance drivers.
