Thermal conductivity of highly porous ceramic foams with different agar concentrations

This paper discussed the creation of ceramic foams with various amounts of agar added. The foams used fly ash as the raw material in order to make them more environmentally friendly. The authors hoped that this successful use of fly ash could help to recycle that vast amounts of it that are produced each year. The effect of the various agar additions on the thermal conductivity of the foams was ...

Porous thermal insulation materials derived from fly ash using a foaming and slip casting method         

Coal fly ash was used as the base material for the formation of thermal insulation materials. The porosity of the produced materials ranged from 86.3-94.5 vol. %. The insulating materials were prepared by ball milling, followed by foaming assisted by the addition of K12, casting and drying, and finally sintering. No harmful chemicals were released to the environment during their preparation. It was found that the thermal conductivity of the samples ...

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....

Thermal conductivity of highly porous mullite materials

Porous materials have widespread industrial applications. In this study, mullite materials with porosities between 72-86 vol% were fabricated and a thermal analyzer (TPS) measured their thermal conductivity using the transient plane source (TPS) technique. Results showed that as the porosity of the mullite materials decreased, thermal conductivity increased....

Porous mullite ceramics with low thermal conductivity prepared by foaming and starch consolidation

Using industrial grade mullite powder and a foaming and starch consolidation process, a series of porous mullite ceramics were prepared. These ceramics were analyzed by a thermal constants analyzer, and it was determined that the ceramics had low thermal conductivities and would make good thermal insulators. The porosity of the synthesized ceramics can be controlled by the sintering temperature and by adjusting solid loading. The ceramics were subjected to theoretical ...
