“…Although mullite is one of the mineralogical components of coal fly ash, the amount of mullite in coal fly ash is rather small. As such to increase the mullite content, aluminum source such as alumina [9][10][11][12], aluminum hydroxide [12,13], aluminum sulfate [14,15], aluminum dross [16], and bauxite [17][18][19][20][21][22][23][24][25][26] was added to the coal fly ash. However, some studies [28,29] showed that it is possible to produce a high crystalline mullite ceramic with no extra aluminum sources.…”

Some industrial wastes are shown to be useful in the production of mullite ceramics. These industrial wastes are rich in certain metal oxides such as silica (SiO2) and alumina (Al2O3). This gives wastes the potential to be used as a starting material source for mullite ceramics preparation. The purpose of this review paper is to compile and review various mullite ceramics preparation methods that utilized a variety of industrial wastes as starting materials. This review also describes the sintering temperatures and chemical additives used in the preparation and its effects. A comparison of both mechanical strength and thermal expansion of the reported mullite ceramics prepared from various industrial wastes were also addressed in this work.

“…Huang et al [30][31][32] first reported the preparation of mullite from the fly ash and alumina mixture. Recently, Jung et al [33] have successfully synthesized 3YSZ-doped mullite ceramics from waste fly ash and submicron Al 2 O 3 powders with 3YSZ. In the previous research, industrial grade Al 2 O 3 powders were added as alumina sources for mullitization.…”

“…The coal fly ash contains a variety of impurities such as Fe 2 O 3 , Na 2 O, K 2 O, P 2 O 5 , MaO, CaO, MgO and TiO 2 [7], thus it is difficult to directly extract pure Al 2 O 3 by a simple acid or alkali treatment. One method of obtaining high purity alumina from coal fly ash, is therefore to manufacture alum as an intermediate product.…”
