Porous mullite ceramics were prepared via foam-gelcasting using industrial grade mullite
powder as the main raw materials, Isobam-104 as the dispersing and gelling agent, sodium …

The paper introduces a new kind of thermal insulation material using coal fly ash as main
raw material by the method of foaming and slip casting process. The foaming ability of the …

Natural materials, such as bone and abalone nacre, exhibit exceptional mechanical
properties, a product of their intricate microstructural organization. Freeze casting is a …

Glass–ceramic foams were fabricated at a relatively low temperature by incorporating coal
gangue, waste quartz sand and sintering additives in different proportions. Sintering and the …

In this work, the preparation of foam-gelcasting was simplified with a copolymer of
isobutylene and maleic anhydride (Isobam), avoiding the traditional gelling system including …
