ResumoAbstract Mechanical alloying was used to prepare molybdenum carbide. Microstructural characterization of samples was performed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) methods. Molybdenum carbide was heated at 800 °C for 15 min in order to produce carbon nanotubes. Nanoparticles of about 50–140 nm in diameter and nanotubes with diameters of about 70–260 nm and 0.18–0.3 μm in length were obtained after heating at 800 °C, by means of this process.
