Method for producing tungsten carbides by gas-phase carburization |
| 摘要 |
The invention relates to a method for producing wolfram carbides by gas-phase carburetion of wolfram powders and/or suitable wolfram precursor compounds in powder form at temperatures above 850° C. According to the method a CO<SUB>2</SUB>/CO mixture with a CO<SUB>2 </SUB>content greater than the Boudouard equilibrium content corresponding to the carburetion temperature is used as carburetion gas phase.
