VERFAHREN ZUR HERSTELLUNG VON WOLFRAMKARBIDEN DURCH GASPHASENKARBURIERUNG
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 CO2/CO mixture with a CO2 content greater than the Boudouard equilibrium content corresponding to the carburetion temperature is used as carburetion gas phase.
