The thermionic emission properties of bulk HfC were measured at 1300 to 2100 deg K. The experimental apparatus, in addition to the external instrumentation, consisted of a plane diode with a copper collector and a hafnium carbide emitter. The saturation emission current was measured as a function of temperature with a constant voltage of 95 v applied to the collector, which was spaced about 1 mm from the emitter. An approximate least-squares fit to the experimental poiitts gives a work function of 4 v and a Richardson constant of 40 amp/cm2 deg2. A Richardson plot of the experimental data is given.
