The temperature dependence of the thermal properties (specific heat,Cp, thermal diffusivity,a, and thermal conductivity,K) of endellite clay has been investigated over the temperature rangeR·T⩽T≲/280 °C using the plane temperature wave technique. The experimental results showed that in the initial stage of temperature rise botha andK diminish exponentially with increasing temperature up to ∼100 °C. Above 100 °C, the thermal parameters are found to reach stable values, namely,Cp=0.22±0.008 cal g−1 deg−1,a=(5.0±0.18)−10−4 cm2 sec− 1 andK=(2.2±0.16) · 10−4 cal cm−1 sec−1 deg−1. The explanation of the results was supported by using DTA and TG analysis.
