Fiber-coatings for fiber-reinforced mullite/mullite composites
Le Journal de Physique IV, 2001Mullite-based fiber-reinforced composites are favorite candidates for the application in combustion chambers of gas turbines. The application requires damage tolerance, temperature and oxidation-resistance at high temperatures (>1200°C) over long terms. In order to realize crack deflection and fiber pull-out, an interphase coating of the mullite fibers

Diffusion bonding of ceramics: mullite, ZrO2-toughened mullite
Journal of Materials Science, 1991Diffusion bonding of fine-grained mullite and ZrO2-toughened mullite was performed in the temperature range from 1500 to 1550 °C in air. Uniaxial pressure was applied at high temperature during the bonding process. The surface roughness to be bonded (Rmax) was about 3 μm. Bonding strength was measured by four-point bending tests and the strength of the

Mechanical behaviour of mullite composites reinforced with mullite fibres
Materials Science and Engineering: A, 1995Abstract Mullite matrix composites uniaxially reinforced with uncoated and BN (0.3 or 1 μm thick) coated mullite fibres were consolidated to 82 to 98% of TD (theoretical density) at 1300 °C by using a colloidal processing route to make mullite matrix.

Tape Casting and Properties of Mullite and Zirconia–Mullite Ceramics
Journal of the American Ceramic Society, 1991Mullite and ZrO 2 ‐mullite ceramics have been prepared by tape casting mixtures of Al 2 O 3 , quartz, and ZrO 2 powders and subsequent reaction sintering. Tape casting leads

Reactive Coating of Zircon on Mullite and Mullite—Alumina Substrates
Journal of the American Ceramic Society, 1997A stable zirconia coating of 20–30 pm thickness on a mullite substrate with a different alumina/silica ratio was obtained by reactive coating of zircon. It is shown that the Al 2 O 3 / SiO 2 ratio of the mullite ...

Despite technological importance, limited information is available on the correlation of major processing variables with the sintering behavior and microstructure development of aluminum silicates containing mullite as the principal phase. Recent studies illustrate the excellent mechanical properties of mullite and the importance of controlled ...

Processing of diphasic mullite and mullite-alumina composite precursors
2021Diphasic mullite and mullite-alumina composite precursors were prepared from the silica source (Na2SiO35H20) (a cheap industrial by-product) and the alumina source (AlCl36H2O) by a coprecipitation method (aluminium nitrate and colloidal silica were used to prepared mullite-alumina composite precursor as a comparison), aiming to understand the mullite ...
