Niobium carbide (Nb₂C) is a refractory ceramic compound belonging to the transition metal carbide family, characterized by extremely high hardness and melting point. It is employed in cutting tool inserts, wear-resistant coatings, and high-temperature structural applications where conventional metals fail; engineers select it over tungsten carbide or titanium carbide when superior hardness combined with chemical inertness and thermal stability are required in extreme environments.
