<p>In a process for producing fine-particle transition metal carbides of vanadium, niobium, tantalum und tungsten or mixtures thereof, a) a complex compound of the transition metal or mixtures thereof containing a metal are reacted with a polymer compound containing carbon, b) the reaction product from step a) is dried and pyrolysed to yield the fine particle transition metal and carbon, c) the pyrolysis products of step b) are converted to the corresponding carbides at 1200 to 1600°C. The transition metal carbides of vanadium, niobium, tantalum and tungsten so obtained are characterized by the extreme fineness of their particles.</p> |
