Thermophysical properties of NbCsub(x)

The thermal conduction, specific heat, temperature conductivity and electric resistance of the NbCsub(X) compound (C/Nb=0.77; 0.82; 0.94) were measured in the range of temperatures between 20 and 900 deg C. The Lorenz number and the phonon component of the thermal conduction were analyzed and calculated. It was suggested that the phonon component of the thermal conduction is independent of the temperature, while the electron component increases and governs the temperature dependence of thermal conduction of the NbCsub(x) compound above the Debye temperature
