Carbon-coated nanomaterials have broad application prospects in the field of energy,magnetic storage,chemical catalysis and bio-medical.Generally,carbon-coated nanomaterials can be fabricated by different methods such as arc discharge [1],pyrolysis [2],CVD [3] and detonation [4] et al.In this paper,the method of electrical explosion of metal wire in organic liquid was adopted to prepare carbon encapsulated nanoparticles.In the medium of absolute ethyl alcohol,under the high-voltage pulse current(HVPC),the high purity zirconium wire became fusion,gasification,expansion and explosion and then nanoparticles will form.The energy,voltage and current in the experiments were measured to analyze the influence of them on the products.The products were analyzed by X-ray diffraction technique(XRD),transmission electron microscopy(TEM)and high power transmission electron microscopy(HTEM).The results show that the carbon encapsulated ZrC nanoparticles were fabricated successfully.The diameter range between 10nm-150nm.For the voltage of 4kv,8kv and 12kv,the average size of the products is 24.9nm,41.4nm and 43.9nm,respectively.
