· JVASP-26748· Na2CuSbS3

Na2CuSbS3 is a quaternary sulfide compound containing sodium, copper, and antimony—a material class of interest in solid-state chemistry and materials research rather than established industrial production. This compound belongs to the family of multinary sulfides being investigated for potential applications in photovoltaics, thermoelectrics, and other semiconductor devices, where mixed-metal chalcogenides offer tunable electronic properties. Research on such materials is driven by the need for earth-abundant alternatives to conventional semiconductors, though Na2CuSbS3 remains primarily in the experimental phase with limited commercial deployment.
