Synthesis of tungsten carbide nanoparticles by hydrothermal method and its Characterization

Tungsten carbide (WC) nanoparticles were synthesized by hydrothermal method and their structural characterization was performed by using powder X-ray diffraction, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). SEM and TEM study revealed their morphology and the particle size of WC nanoparticle respectively. Dielectric properties of WC nanoparticles were determined by using LCR meter at different frequencies and different temperatures. Dielectric constant, dielectric loss, and electrical a. c. conductivity were measured. Electronic properties such as valence electron plasma energy, average energy gap or Penn gap, Fermi energy, and electronic polarizability of the WC nanoparticles were also estimated.
