Zirconium carbide nanoparticles were produced by wire explosion process by exploding zirconium conductor in methane ambiance. X-ray diffraction studies of the particles produced by wire explosion process confirm the formation of cubic zirconium carbide particles. The results of the study indicates that unreacted zirconium content in the zirconium carbide powder could be reduced by exploding the zirconium conductor by depositing energy of three times the sublimation energy in 100 kPa methane pressure. Selected area electron diffraction (SAED) analysis confirms that particles produced are cubic zirconium carbide particles. Transmission electron microscopy analysis indicates that zirconium carbide nanoparticles are spherical in shape and the particle size distribution follows log-normal distribution with the mean particle size of about 20 nm.
