· JVASP-12798· Na3GaS3

Na3GaS3 is an inorganic ceramic compound composed of sodium, gallium, and sulfur, belonging to the family of thiogallate materials. This is primarily a research and development compound rather than an established commercial material; it is investigated for potential applications in solid-state ionics and photonic materials due to its ionic crystal structure and semiconductor properties. The material is of particular interest in the solid electrolyte and optoelectronic research communities, where sulfide-based ceramics are being explored as alternatives to oxide systems for applications requiring specific ionic conductivity, thermal stability, or optical response characteristics.
