Preparation of porous mullite ceramics with low thermal conductivity 

This study analyses a mullite ceramic formed through foaming and starch consolidation of mullite powder, and how its thermal conductivity changes with porosity of the ceramic. The thermal conductivity was measured through the transient plane source (TPS) method with the TPS. As the porosity of the mullite ceramic increases so does the thermal conductivity....

Carbon nanotubes based engineering materials for thermal management applications

As nanotechnology becomes increasingly important, researchers are investigating methods to decrease the size of electronics. Carbon nanotubes (CNTs) have potential applications in nanoelectronics because of their high thermal conductivity and miniscule size. This study had many focuses, but a TPS used the transient plane source method to specifically measure the thermal conductivities of CNT-fabricated thermal pastes. Results showed that the thermal conductivities varied depending on filler content, but were comparable ...

Thermal conductivity of nanoporous glass alumina film and composites

The thermal conductivity of nanoporous glass alumina films (NGAFs) were theoretically and experimentally studied in this paper. The thermal conductivity of pristine NGAFs and silver nanowire-infused NGAFs of various pore sizes and porosities were measured with a thermal constants analyser based on the transient plane source (TPS) method. Theoretical and experimental results were consistent with one another, and indicated that the pore radius and porosity of the films influenced thermal ...

Characterization of anisotropic and irregularly-shaped materials by high-sensitive thermal conductivity measurements

The transient plane source (TPS) technique has a wide range of applications because of its capability to test solids, liquids, powders, and anisotropic materials over a range of sizes. Thermal properties of thin films and coatings can also be characterized using the TPS method if the samples are placed between the sensor and a bulk background. To minimize errors with the TPS method, use identical materials on each side of ...

Thermal behaviour of sol-gel derived phosphate ceramics

Phosphosilicate ceramics with varying compositions were synthesized through the sol-gel process and the thermal conductivity of the samples was measured using the transient plane source (TPS) method. Results showed that the thermal conductivity of phosphosilicate ceramic powder was low, but increased slightly with phosphorous concentration. The low thermal conductivity of the ceramics could be useful in thermal barrier applications....
