The quest for lightweight and functional materials poses stringent requirements on
mechanical performance of porous materials. However, the contradiction between high …

Porous ceramic fiber membranes with high gas permeance have shown great potential for
the treatment of dust-laden gas. However, a major challenge is posed by the micro or nano …

Abstract The porous SiC-Mullite porous ceramics with different pore size were prepared by
SiC particles, kaolin, Al (OH) 3, and flake graphite, V 2 O 5 and AlF 3 were used as …

Aerogels, with ultra-low density and thermal conductivity, are key materials for the
development of high-efficient thermal insulations. Yet, their low compressive strength …

Porous has been formed in samples when mullite whiskers are prepared by firing compacts
of high-aluminum fly ash and ammonium aluminum sulfate hydrate with a small amount of …

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 …

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

Mullite fiber-based porous ceramics have been widely used in the field of heat insulation. To
further broaden their applications in other fields, such as filtration and sound absorption …
