Using the transient plane source (TPS) technique, researchers measured the thermal conductivity, thermal diffusivity and specific heat capacity of an electrically insulating ceramic material prepared from kaolin and feldspar. The electroceramic was tested at multiple temperature points to see how it affected thermal conductivity. Thermal properties were strongly affected by temperature, and the ceramic material studied had the highest thermal conductivity and thermal diffusivity at the highest temperature tested. The ...
The development of hydrogen storage materials for use in light-duty vehicles is investigated in this paper, which is still a ways off until commercial use. High-pressure metal hydrides (HPMH) are specifically studied here, at varying temperatures. The transient plane source (TPS) technique is used to measure the thermal conductivity and specific heat of the prepared hydride materials. Porosity and density are also important physical factors to consider when dealing with ...
The authors set out to prepare cellular vitreous carbon (CVC) foams with varying thermal and physical properties. This was accomplished by using tannin-based resin modified by different isocyanates in varying amounts. Three different experimental procedures were used to prepare foams with different physical and thermal properties. Physical properties of the foams studied include density, as well as pore volume, pore size and cell diameter. The transient plane source (TPS) technique ...
Very porous ceramics were prepared by the direct foaming method containing 79% kaolinite , based on commercial clay. Ceramics were prepared with different pore volume fractions, and the different ceramics were analyzed using the transient plane source (TPS) technique to measure thermal conductivity. Increasing pore volume fraction led to decreased thermal conductivity....
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....
