Preparation of Porous Mullite Ceramics Using Fly Ash Cenosphere as a Pore‐Forming Agent by Gelcasting Process

This article discusses the creation of a porous mullite ceramic through the incorporation of fly ash cenospheres (FAC) into mullite powder through the gelcasting process. Sintering temperature and the amount of FAC added were investigated as factors affecting density and strength. The authors found that the porous mullite ceramics had a high strength, and high porosity (48.1-72.2%) Thermal conductivity was measured and was determined to be 0.16-0.22 W/mK....

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 ...
