The Metallurgical and Materials Engineering Dept. at Montana Tech, through research funded by the Army Research Laboratory, is investigating a method for the synthesis of nanocrystalline tungsten carbide (WC). Tungstate (WO42-) anions were adsorbed from an aqueous solution onto an activated carbon matrix. The tungsten-loaded carbon was then heated under an argon atmosphere to promote the formation of tungsten carbide. Carburized samples were characterized using X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Submicron crystals of WC and W2C were identified in samples carburized under argon at 1000 °C for 20 hours. Future work will involve statistical optimization of both tungstate adsorption and carburization, as well as reducing operating temperatures and reaction times through the application of reducing and reactive gas atmospheres, developing a method for separating the nanocrystals from the residual carbon matrix, and applying the optimized synthesis method for other carbides of interest (TiC, NbC, TaC, etc.).
