· JVASP-21556· Na5SnAs3

Na5SnAs3 is an inorganic ceramic compound belonging to the family of mixed-metal arsenides, combining sodium, tin, and arsenic in a defined stoichiometric ratio. This is a research-stage material studied primarily for its structural and electronic properties rather than as an established engineering material; compounds in this family are of interest for solid-state chemistry, potential semiconductor applications, and fundamental materials science investigations into ternary metal-arsenide systems.
