Thermal Conductivities of Mono-carbides in Transition Metals

Abstract

The thermal conductivities of the mono-carbides having NaCl type structure in several transition metals of the fourth and fifth groups on the periodic chart were measured at 0°C and at the liquid-oxygen temperature. For these substances, larger conductivity by lattice than those by conduction electrons is concluded from the calculations of the Wiedemann-Franz ratio. The values of the measured thermal conductivity are compared and systematically discussed wich reference to the periodic chart.
