Nb₃B₄ is a niobium boride intermetallic compound belonging to the refractory metal boride family, valued for its combination of high hardness and structural rigidity at elevated temperatures. This material is primarily investigated in research and advanced manufacturing contexts for applications requiring exceptional wear resistance and thermal stability, where traditional steel or nickel-based superalloys reach their performance limits. Engineers consider niobium borides as candidates for extreme-environment components because the niobium-boron system offers superior hardness compared to many conventional tool materials and maintains mechanical integrity in harsh conditions, though commercial adoption remains limited compared to more established ceramics and composites.
