Combustion reactions of transition metal oxides (WO3, MoO3, Ta2O5, Nb2O5, ZrO2, and TiO2), magnesium, carbon, and sodium fluoride produce a range of nanostructured transition metal carbides (W2C, Mo2C, TaC, NbC, ZrC, and TiC) with low amounts of free carbon. Sodium fluoride improves unfavorable combustion regimes and facilitates the carburization of metal carbides. The average particle size of carbides...
