Fabrication and properties of silica-based ceramic cores modified by mullite powders with different particle sizes

Journal of Aeronautical Materials, 2021
Ceramic cores provide complex internal cavity structures in the investment precision castings of hollow blades for aero-engine. The silica/mullite ceramic cores were fabricated by hot injection molding, adding fused mullite powders with different ...

Preparation of mullite whiskers reinforced SiC/Al2O3 composites by microwave sintering [PDF]

Processing and Application of Ceramics, 2016
Mullite whiskers reinforced SiC/Al2O3 composites were prepared by microwave sintering in a microwave chamber with TE666 resonant mode. Original SiC particles were coated with SiO2 using sol-gel processing and mixed with Al2O3 particles.

Comparison of solidification behavior of synthetic mullite and mullite-forming raw materials by aero-acoustic levitation

Open Ceramics, 2023
Fused mullite is used in refractories and as an abrasive due to its suitable properties. Mullite is formed over a wide range in the Al2O3–SiO2 phase system, preferably as 3:2 or 2:1 mullite.

Solid-state NMR characterisation of the thermal transformation of a Hungarian white illite [PDF]

, 2005
1H, 27Al, 29Si and 39K solid-state NMR are reported from a Hungarian illite 2:1 clay for samples heated up 1600 °C. This single-phase sample has a small amount of aluminium substitution in the silica layer and very low iron-content (0.4 wt%).

A novel hollow alumina sphere-based ceramic bonded by in situ mullite whisker framework

Materials & Design, 2020
In this study, a novel hollow alumina sphere-based ceramic enhanced by in situ mullite whisker framework was recommended. Hollow alumina spheres selected as the main pore-forming agent were bonded together by an active mullite powder at high temperature.
