Abstract:A simple and rapid process has been developed that allows the preparation of NbC-C composite rods. Graphite rods are impregnated with an ethanolic solution of NbOCl2 and resistively fired (> 1900°C) under an argon atmosphere. The final composite product is found to contain residual carbon particles within a NbC-C matrix.
Keywords:niobium    carbides    carbon    composites    precursors
