In the case of tungsten carbide ground for 48 h under water, after annealing for 4 h at 900C in dry hydrogen, he obtained the following gas composition: methane 008, CO 001, and CO2 0005 vol.-%. With tungsten carbide +20% cobalt under the same conditions, the composition was: methane 026, CO 0007, and CO2 0002 vol.-%.
