The rapid synthesis of tungsten carbide through the use of microwave-assisted techniques is demonstrated. Examination of the obtained samples reveals a single-phase structure. The influence of the amount of carbon precursor added to the synthesis is investigated (see figure), providing insight into the mechanism of tungsten carbide formation. The method has potential for scale-up and synthesis of other metal carbides.
