A method called the "multicurrent" transient hot-wire method has been developed for measuring thermal conductivity and diffusivity simultaneously and with accuracy. The method can be applied to specimen materials in liquid and solid states, and can be used with a wide range of temperatures. The principle of the hot-wire method is to measure the time variation in the temperature of an electrically heated wire enclosed in a specimen by utilizing the wire as a resistance thermometer. By using various electric heating current values, the convenience and accuracy of the method are greatly improved. As an example of this type of measurement, superionic conducting glass (AgI)0.5(AgPO3)0.5 was chosen as specimen material, and the thermal conductivity and diffusivity were measured in a temperature range including the glass transition. The experimental results are analyzed and briefly discussed on the basis of the gas kinetics theory of phonon conduction in solids.
