ceramic

· JVASP-58992· Na5InS4

Na5InS4 is an inorganic ceramic compound belonging to the sulfide ceramic family, combining sodium, indium, and sulfur in a defined stoichiometric ratio. This material is primarily of research and development interest rather than a widely commercialized engineering ceramic, with potential applications in solid-state ionic conductors and advanced electrolyte systems where its sulfide chemistry may offer ionic transport properties. The compound represents exploration within the broader class of chalcogenide ceramics, which are being investigated for next-generation energy storage and electrochemical device applications where traditional oxide ceramics show limitations.
