· JVASP-12956· Na2CS3

Sodium tricarbide sulfide (Na2CS3) is an inorganic ceramic compound containing sodium, carbon, and sulfur. This material is primarily of research and specialized industrial interest rather than a commodity engineering ceramic, with applications emerging in solid-state chemistry and materials research focused on sulfide-based ionic conductors and energy storage systems. Its notable characteristics stem from its ionic nature and potential utility in solid electrolytes for batteries and other electrochemical devices where sulfide ceramics offer advantages over oxide alternatives.
