Interface engineering in mullite fiber/mullite matrix composites

Journal of the European Ceramic Society, 2008
Mullite fiber/mullite matrix composites are attractive because of their inherent oxidation resistance at high temperatures. Mullite has better creep resistance than alumina. However, chemical interactions between oxides are often very severe; with the result no gain is made over monolithic mullite in terms of toughness.

Mullite and mullite-type crystal structures

International Journal of Materials Research, 2012
Abstract Synthetic mullites (Al4+2 x Si2 –2 x O10 – x ) belong to one of the most important groups of ceramic materials.

Mullite

2022
Abstract Mullite is an important material since it is a major component of all alumino-silicate ceramics. It has a stability field intermediate in composition between sillimanite Al2SiO5 and alumina Al2O3. Diffuse scattering data display a rich diversity of detail.

Crystallization studies in mullite and mullite–YSZ beads

Journal of the European Ceramic Society, 2010
Abstract Mullite and mullite/Y-ZrO2 (25 and 50 vol.%) beads were produced by thermal spraying in water the corresponding atomised compositions. The amount of amorphous phases in the as-sprayed beads was comparatively determined by X-ray diffraction (XRD) and differential thermal analysis (DTA) methods.

Mullite/molybdenum composites

Composite Interfaces, 1998
The possibility of fabricating continuous mullite/Mo FGMs with density closed to theoretical, by pressure slip casting of proof ethyl alcohol based slurries has been shown. Dense (> 98 th%) homogeneous mullite/Mo (32 vol%) composites with two Mo average grain sizes (1.5 and 3 μm) have been obtained at 1650°C in vacuum and under reducing conditions ...

Nanocomposite Mullite/Mullite Powders by Spray Pyrolysis

Journal of Nanoparticle Research, 1999
A mullite/mullite nanocomposite powder has been synthesized, composed of nanometer-size 3Al2O3 2SiO2 (‘3 : 2’) mullite precipitates within a matrix of the high alumina 2Al 2O3 SiO2 (‘2 : 1’) mullite. Historically, the transition from the metastable high-alumina phase to the thermodynamically stable ‘3 : 2’ phase of mullite has been thought to be a ...
