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 ...Read More
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 ...
