Using coal fly ash slurry samples supplemented with different amounts of Al 2 O 3, we
fabricated mullite-based porous ceramics via a dipping-polymer-replica approach, which is …

Mullite precursors, waste flyash coated with aluminum hydroxide, were used to prepare low
cost porous mullite-based ceramics by reaction sintering. The samples with different alumina …

The objective of this study was to prepare highly porous mullite ceramics with relatively large-
sized pores and improved compressive strength using a freeze/gel casting route combined …

Fly ash is a typical industrial solid waste that seriously affects human health and ecological
balance. In order to recycle the fly ash, in this work, porous mullite ceramics were …

A freeze–gel casting method has been proposed to fabricate porous mullite–alumina
composite with controlled 'designer'pore structure and improved compressive strength. In …

Porous mullite ceramics were fabricated from an industrial grade mullite powder by
gelcasting process using fly ash cenospheres (FAC) as a pore‐forming agent. The influence …

Different alumina sources (Al (OH) 3, Al 2 O 3, and boehmite) were used to prepare mullite-
based ceramics from milled coal fly ash. The effect of alumina source and sintering …

Porous mullite ceramics with a fully closed-cell structure were fabricated by direct
coagulation casting (DCC) using fly ash hollow spheres (FAHSs) as the non-sacrificial pore …

In this communication, high-strength mullite ceramics was prepared from bauxite and high-
aluminum fly ash that is a by-product of coal combustion in thermal power plants. The effects …

With the aid of dry pressing method, porous mullite ceramic supports were prepared
successfully using desiliconized high alumina fly ash as main raw material, kaolin and …
