The thermal conductivity and thermal diffusivity of lithium sulphate were measured using the transient plane source (TPS) technique in the temperature range from 300 to 900 K.It was determined that thermal conductivity decreases up to 640 K, but rises past this temperature. A similar trend was observed for thermal diffusivity....
A series of Er and Y sintered compounds were prepared and were subsequently tested for their thermal conductivity and electrical resistivity. The transient plane source (TPS) technique was used for the thermal conductivity measurement. These compounds were designed for use as superconductors and the authors wanted to study the electron-phonon interaction near the vicinity of Tc....
The ceramic Cecorite 130P was analyzed using the transient plane source (TPS) technique in order to measure the thermal conductivity in the range from 88 to 280 K. Fused quartz samples were also investigated in order to ensure the technique worked at liquid nitrogen temperatures. The thermal conductivity of Cecorite 130P was determined to have a slight dependence on temperature, with a maximum around 170 K....
The authors describe the dynamic plane source, a transient method of measuring the thermal conductivity, diffusivity and specific heat of a sample. This method uses a sensor, and relies on the premise of an adiabatic system. Using this method, the thermal properties of cast iron, pure iron and stainless steel are measured. The experimentally obtained values match with the literature values quite closely....
This work introduces a direct method for measuring the specific heat of solids, using the Transient Plane Source Technique (TPS). To begin, a sample is placed into a thermally conductive holder, surrounded by a thermally insulating material. A thermally conductive sample holder is used, to limit the time it takes to achieve a temperature equilibrium between the holder and the sensor. Insulating the sample holder is to minimize heat loss ...
