· JVASP-45356· Na6P4W

Na6P4W is a complex intermetallic compound containing sodium, phosphorus, and tungsten, representing a rare combination of light and refractory elements. This material belongs to the family of multi-component metal phosphides and appears to be primarily of research interest rather than established industrial production, with potential applications in high-temperature catalysis, energy storage, or advanced structural composites where the tungsten component provides thermal stability.
