· Na4CdP2

Na₄CdP₂ is an inorganic ceramic compound containing sodium, cadmium, and phosphorus, belonging to the family of phosphide ceramics. This material is primarily investigated in solid-state chemistry and materials research rather than established in mainstream industrial production. It is of academic interest for potential applications in solid electrolytes, photovoltaic devices, and other advanced ceramic systems where phosphide-based compounds show promise for ion conductivity or electronic functionality.
