Abstract
Thermal diffusivity of low conducting materials is measured by detecting the thermal expansion of a cylindrical specimen heated at one base, in contact with a copper disc. The simultaneous recording of the temperature of the copper and of the capacitive signal by which one can measure the dilation of the specimen allows the experimental determination of thermal diffusivity without the uncontrolled heat losses which usually occur due to temperature sensors.
