Abstract:

Values of heat conduction coefficients for W and graphite at various temperatures were obtained experimentally and theoretically. The heat conduction coefficients decreased with rise in temperature for both materials between 900 and 2200 C. The specific electric resistance of these substances increased through the range 9002200 C. The Lorentz number for W between 900 and 2200 C is above the theoretical value and depends approximately upon temperature.
