· NbO

Niobium monoxide (NbO) is a refractory ceramic compound belonging to the transition metal oxide family, characterized by high hardness and thermal stability. It is primarily investigated in materials research for high-temperature structural applications and as a constituent in advanced ceramic composites, though industrial adoption remains limited compared to established alternatives like alumina or zirconia. NbO is notable for its potential in extreme-environment applications where both mechanical robustness and resistance to oxidation at elevated temperatures are critical.
