Mullite, an intermediate phase of the binary alumina-silica system, is one of the most
important phases of ceramic products containing alumina and silica in the initial …

We report a method to produce processable Pickering emulsions in which electrostatic
heteroaggregation of oppositely charged fumed silica and alumina particles is exploited …

The in situ reaction between alumina and silica to obtain mullite (Al6Si4O13) can be
significantly affected by using synthetic amorphous silica (SAS) sources instead of …

The effect of precursor powders using aluminium sulphate/boehmite and colloidal silica on
the green compact, mullitization, densification, microstructure and mechanical properties …

Ceramic porous structures are technologically important materials for several high-
temperature applications. Many recent studies have aimed at increasing their temperature of …

Kaolin Kga-1b and a muscovite from Bihar (India) and their mixtures were used to
investigate the densifying mechanisms during the sintering. The kaolin–muscovite mixtures …

Mullite of stoichiometric composition has been synthesized by sol-gel process. Aluminium
nitrate and ethyl silicate are used as the starting materials to prepare the single phase …

Monophasic mullite precursors with composition of 3Al2O3· 2SiO2 (3: 2) were synthesized
and then were sintered by Spark Plasma Sintering (SPS) to form transparent mullite …

The effect of alumina component in diphasic mullite precursors containing alkoxy-derived
silica on the crystallization and sintering behavior of compacts was studied. The phenomena …

Analytical investigations using Scanning Electron Microscopy (SEM), with Energy Dispersive
