Niobium boride (NbB) is a refractory ceramic compound combining niobium metal with boron, belonging to the family of transition metal borides known for exceptional hardness and high-temperature stability. It is primarily investigated in research and advanced manufacturing contexts for applications requiring extreme wear resistance and thermal durability, particularly where conventional hard coatings or tool materials reach their performance limits. The material competes with titanium boride, tungsten carbide, and other refractory borides in specialized cutting, coating, and high-temperature structural applications.
