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 ...
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 ...
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 ...
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, ...
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 ...
