Summary: | The invention relates to a method for producing wolfram carbides by gas-phas e carburetion of wolfram powders and/or suitable wolfram precursor compounds i n powder form at temperatures above 850 ~C. According to the method a CO2/CO mixture with a CO2 content greater than the Boudouard equilibrium content corresponding to the carburetion temperature is used as carburetion gas phas e. |
