The effect of different concentrations of graphite (0, 2%, 4%, 6%, 8%) on sinter density and thermal conductivity of the compounds was studied. The results indicated that the sintering density decreased with increasing graphite concentrations by 16.75%, and the thermal conductivity decreased at a rate of 25.90%. This decrease in thermal conductivity is due to the low thermal conductivity of both WC and graphite.
