中文摘要

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 900s in a domestic microwave oven.
