· SrH2

Strontium hydride (SrH2) is an ionic ceramic compound belonging to the metal hydride family, characterized by a simple crystal structure with relatively high density. While not widely commercialized as an engineering material, SrH2 is primarily of interest in research and advanced applications including hydrogen storage systems, thermal energy storage, and as a precursor for synthesizing other strontium-containing ceramics and compounds. Its potential lies in hydrogen economy applications where metal hydrides serve as solid-state hydrogen carriers, though practical adoption depends on optimizing kinetic performance and cycle stability compared to competing hydride systems.
