· JVASP-35082· Sr2H3I

Sr2H3I is an experimental ceramic compound composed of strontium, hydrogen, and iodine, belonging to the family of mixed-anion ceramics with potential ionic or hybrid properties. This material exists primarily in research contexts rather than established industrial production, with interest focused on understanding how hydrogen and iodide ions influence mechanical and transport properties in strontium-based ceramics. Research on such compounds typically targets next-generation applications in solid-state ionics, energy storage, or specialized optical/thermal materials where unconventional anion combinations may offer performance advantages over conventional ceramics.
