中文摘要	By a novel solid-state reaction process using amorphous C(3)N(4)(a-C(3)N(4)) and transition metal oxides as starting reagents, Cubic TaC, NbC and hexagonal WC nanoparticles were successfully synthesized at 1150 degrees C. The products were characterized by power X-ray diffraction (XRD), field-emission scanning electron microscope (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM) and high-resolution TEM (HRTEM). The experimental results show that a-C(3)N(4) obtained by the reaction between C(3)N(3)Cl(3) and Li(3)N is a highly efficient carburation reagent and the transition metal oxides are completely transformed into the corresponding metal carbide nanoparticles at 1150 degrees C, respectively, which is significantly lower than that reported for the traditional preparation of carbides, typically > 1600 degrees C. The TaC, NbC and WC nanoparticles are found to have an average particle size of 10 nm, 15 nm and 8 nm by TEM observation, respectively.
