· ZnP2

Zinc phosphide (ZnP₂) is an inorganic ceramic compound belonging to the phosphide family, characterized by a zinc cation bonded to phosphorus anions in a defined crystal structure. While primarily studied in research contexts for semiconductor and photovoltaic applications, ZnP₂ has potential in optoelectronic devices and as a precursor material for functional coatings. Its relatively high density and semiconductor properties make it of interest for specialized applications where phosphide ceramics offer advantages in thermal stability or electronic functionality over conventional oxides.
