Abstract
The thermal conductivity of a Cordierite-based ceramic is investigated within the temperature range 88 to 280 K using the recently developed transient plane source (TPS) technique. Measurements on fused quartz samples were performed to demonstrate that this experimental technique can be used down to liquid nitrogen temperature. The measurements on Cecorite 130P showed that the thermal conductivity is influenced by the thermal history of the sample. The results are neatly fitted to a third-order polynomial with coefficients which depend on the direction of approach to a particular temperature. However, the thermal conductivity of this material still shows a slight dependence on temperature, with a maximum value around 170 K.
