Na3S (sodium sulfide) is an ionic ceramic compound composed of sodium and sulfur in a 3:1 molar ratio. While primarily known as a chemical reagent and industrial intermediate rather than a structural engineering material, Na3S and related sodium sulfides are of growing interest in solid-state battery research, where they serve as solid electrolyte materials or active components in next-generation energy storage systems. Its ionic conductivity and compatibility with alkali metal anodes make it a candidate material in the emerging field of solid-state battery development, though most applications remain in the research and development phase rather than large-scale industrial deployment.
