· JVASP-150167· Na5As4

Na5As4 is an inorganic ceramic compound composed of sodium and arsenic, belonging to the family of alkali metal arsenides. This is a research-phase material with limited commercial applications; it is primarily of interest in solid-state chemistry and materials science for understanding ionic and electronic properties in alkali arsenide systems. Potential applications remain largely experimental, focused on niche areas such as solid electrolytes, thermoelectric materials, or specialized optical/electronic components where sodium arsenides may offer unique phase behavior or ion mobility, though development and safety considerations (arsenic toxicity) currently restrict broader industrial adoption.
