ABSTRACT:
Tungsten carbide is produced by mixing tungsten oxide or ammonium paratungstate with carbon to form a mixture which is substantially reduced in a non-reducing atmosphere in the presence of sufficient carbon to produce a carbon content in the resulting mixture of less than seven percent by weight, and adding sufficient carbon to the resulting reduced mixture to increase the carbon content to at least the stoichiometric amount needed to form monotungsten carbide prior to carburization of the mixture to monotungsten carbide.
