· Mg3N2

Magnesium nitride (Mg₃N₂) is an inorganic ceramic compound and wide-bandgap semiconductor belonging to the metal nitride family. It is primarily investigated in research and emerging applications for its potential as a high-temperature structural material and wide-bandgap semiconductor, offering advantages over conventional ceramics in thermal stability and nitride-based device compatibility. Current industrial adoption remains limited, but its use is expanding in specialized sectors including thermal barrier coatings, catalytic applications, and next-generation semiconductor devices where thermal conductivity and chemical stability are critical.
