Microstructural evolution and densification behavior of porous kaolin-based mullite ceramic
added with MoO 3 were investigated. The results indicated that MoO 3 addition not only …

Hierarchically porous mullite foams were fabricated from coal-series kaolin and Al 2 O 3
slurries by freeze-casting using tert-butyl alcohol (TBA) and water as templates. TBA …

Excessive sintering shrinkage leads to severe deformation and cracking, affecting the
microstructure and properties of porous ceramics. Therefore, reducing sintering shrinkage …

Mullite bonded porous SiC ceramics were synthesized by infiltrating a SiC porous compact
with a liquid precursor of mullite followed by sintering at 1300–1500° C in air. Different …

Porous ceramics are of significant technological interest because of their application as gas
sensors [1], catalyst supports [2], and hot-gas or molten-metal filters [3, 4]. In most of these …

Porous mullite fiber/silica composite was successfully fabricated by a TBA-based gel-
casting, and the influence of mullite fiber content on the composite microstructure and …

The effective utilization of fly ash (FA) as a raw material for ceramics production is performed
on the FA-kaolin mixtures containing kaolins 10% by mass. The mixtures in comparison with …

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 …

High strength lightweight mullite whisker network reinforced ceramic materials was
successfully prepared by firing a bauxite-kaolin-coal fly ash mixture with additions of varying …

Silica sol is widely used in the preparation of mullite-based fiber porous ceramics (MFPCs),
but it aggregates at the top surface of MFPCs during the drying process. This leads to the …
