摘 要：A simple,easy,and low-cost process for the fabrication of tungsten carbide（WC） powder through microwave heating of WO3–C mixtures was developed. Thermodynamic calculations and experimental investigations were carried out for WO3–C and W–C systems,and a formation mechanism was proposed. In the results,for the synthesis of WC,the use of over stoichiometric amount of C together with a specially assembled experimental setup（which effectively retains heat in the system） is necessary. The WC powder is successfully obtained by heating WO3:5C mixture for 900 s in a domestic microwave oven.
