N2 - An apparatus for measuring the thermal diffusivity, electrical resistivity and heat capacity of metals is described. All measurements are performed on the same cylindrical sample, which is kept in high vacuum and externally heated to the desired temperature (100-900°C). Thermal diffusivity is determined from the phase relation of a propagating heat wave created at the ends of the sample by two miniature furnaces. Heat capacity is determined from the rate of temperature rise while the sample is ohmically heated. Electrical resistivity is determined from the voltage drop along the sample, produced by known direct current. The measurements yield accurate values for the determination of the Wiedemann-Franz ratio.
