<p>A molten blend of an alkali metal halide containing tungsten is treated with solid particulate carbonaceous reactants, such as natural flake graphite. Tungsten monocarbide is produced having a large percentage of relatively coarse crystals. The crystal morphology is blocky or thick bladed with some equant forms and the carbon is present in the correct stoichiometric amount of 6.13 % by weight, thus eliminating any need for carbon additions prior to sintering.</p> |
