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 …

High performance mullite ceramics were prepared from high-aluminum fly ash without any
extra materials via a series of steps. The original fly ash was pretreated with alkali and acid …

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 …

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 …

In this study, the effect of the alumina particle size on the formation of mullite using a silica
gel powder and micro-and nano-scale Al 2 O 3 powders as raw materials was investigated …

In this paper, using only high alumina fly ash as raw material and MoO 3 as additive agent,
the high-strength porous mullite ceramics were achieved by in situ mullite whisker growth …

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 …

Mullite-based ceramic tiles were successfully prepared using only high-alumina fly ash
(HAFA) at relatively low sintering temperatures (1100–1400° C). The effects of alkali …

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 …

Low-cost mullite ceramics were prepared from the mixtures of natural bauxite and industrial
waste fly ash. The fired samples, including fly ash, bauxite and their mixture based on the …
