Rheological behavior of aqueous mullite-albumin-methylcellulose systems
(Elsevier, 2017-03-06)
In this work, the thermogelling behavior of aqueous mullite-bovine serum albumin (BSA) suspensions was studied by dynamic rheology in order to determine the experimental conditions that must be used to form mullite green ...
Combined effects of SiO2 ratio and purity on physical properties and microstructure of in situ alumina-mullite ceramic
(2021-01-01)
The in situ formation of mullite (Al6Si4O13) is a complex process based on solid-state reactions strongly affected by the characteristics of Al2O3 and SiO2 sources. This study investigated the combined effects of variable ...

Monolithic diphasic gels of mullite by sol-gel process under ultrasound stimulation
(1998-12-01)
Diphasic gel in the mullite composition was prepared from a colloidal sol of boehmite mixed with a hydrolyzed tetraethoxisilane (TEOS) solution. The boehmite sol was obtained by peptization of a poorly crystallized or very ...

Rheology of aqueous mullite-starch suspensions
(Elsevier, 2011-04-12)
One of the forming methods developed for the manufacture of porous materials by direct consolidation, in which a ceramic suspension consolidates into non-porous molds (e.g. metal molds) by thermogelation of an organic ...
