Abstract

The paper presents a new experimental set-up developed in the JRC-ITU laboratory, enabling thermophysical measurements to be carried out at very high temperatures in a very simple and small pressurised vessel in which the sample is heated by a continuous wave laser, and subsequently submitted to a short temperature pulse. The adopted method is essentially an extension of the Laser-Flash technique, widely used for thermal diffusivity measurements, whereby, in addition, the heat capacity, and hence the thermal conductivity, are simultaneously evaluated from the pulse analysis. Applications are presented on thermal diffusivity and heat capacity of graphite, zirconia and uranium dioxide up to temperatures above 3000 K.
