Niobium - Wikipedia
The main niobium carbide is NbC, an extremely hard, refractory, ceramic material, commercially used in cutting tool bits.
a pressure–constituent (P–x) phase diagram of niobium carbide was constructed, which is plotted in Fig. 3. With the increase in C concentration, the Nb–C system rst undergoes an ortho-rhombic to monoclinic transition and then transforms back to the cubic phase. Moreover, some phases of niobium carbides
