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 …

Mullite-based ceramics were produced entirely from industrial wastes. Aluminum dross (AD)
is a waste product produced in secondary aluminum refining, and coal fly ash (CFA) which is …

Porous mullite ceramics are widely used in heat insulation owing to their high temperature
and corrosion resistant properties. Reducing the thermal conductivity by increasing porosity …

Porous fibrous mullite ceramics with a narrow range of pore size distribution have been
successfully prepared utilizing a near net-shape epoxy resin gel-casting process by using …

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 …

Porous mullite ceramics with improved mechanical strength were fabricated by using a
combined foam-gelcasting and microwave firing method at 1373–1523 K for 30 min. The …

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 …

In this paper, porous mullite/corundum ceramics with high porosity, high strength and low
thermal conductivity were fabricated by foam-gelcasting method using fused mullite powder …

The in-situ mullite (3Al 2 O 3· 2SiO 2) foams are fabricated by 3D printing (direct ink writing
(DIW)) technique and utilize waste rice husk ash (RHA). The Al 2 O 3-SiO 2 inks are …

Porous mullite ceramics with an open/closed pore structure were prepared by protein
foaming method combined with fly ash hollow spheres. Both the open porosity and total …
