Preparation of Mullite Fiber Reinforced Mullite Composites

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract In this paper, mullite fiber reinforced mullite composites were prepared by stitched structural perform, the silica sol and alumina sol. In order to improve the compatibility of mullite fiber and silica sol matrix, interface coating was made by infiltration. The composites were prepared by the method of liquid phase infiltration,

Cobalt incorporation in mullite [PDF]

open access: yesActa Crystallographica Section A Foundations of Crystallography, 2005
Mullite (nominally 3Al_2O_3.2SiO_2) is technologically important material for advanced ceramics applications. Depending on the synthesis procedure, mullite is able to incorporate considerable amounts of transition metal cations [1]. While Cr^3+, Fe^3+ and V^3+ have the strongest tendency of incorporation in mulllite, only low or very low amounts of Fe ...

Influence of size reduction of fly ash particles by grinding on the chemical properties of geopolymers [PDF]

open access: yes, 2018
Chemical properties of geopolymers were evaluated from the reduction of fly ash particle size by grinding. X-ray diffraction determined that at early curing ages new crystalline phases appear in the matrix of the geopolymer and they remain for 28 days ...
