· JVASP-10106· K4SnO4

K₄SnO₄ is an inorganic oxide ceramic compound containing potassium and tin, belonging to the family of mixed-metal oxides studied primarily in materials research rather than as an established commercial material. This compound is of interest in solid-state chemistry and materials science contexts, particularly for investigations into crystal structure, ionic conductivity, and potential applications in electrochemical or catalytic systems. As a research-phase material, K₄SnO₄ represents the broader potential of tin-based oxides in advanced ceramics, though it has not achieved widespread industrial adoption compared to more conventional tin oxide ceramics like SnO₂.
