Effects of the water quantity on the solventless TEOS hydrolysis under ultrasound stimulation
(Kluwer Academic Publ, 2000-01-01)
The acid hydrolysis under ultrasound stimulation of solventless tetraethoxysilane(TEOS)-water mixtures was studied at 40 degrees C, by means of a heat flux calorimetric method, as a function of the initial water/TEOS molar ...

A dissolution and reaction modeling for hydrolysis of TEOS in heterogeneous TEOS-water-HCl mixtures under ultrasound stimulation
(Elsevier B.V., 2002-07-01)
A simplified dissolution and reaction modeling was employed to study the hydrolysis of heterogeneous tetraethoxysilane (TEOS)-water-HCl mixtures under ultrasound stimulation. The nominal pH was changed from 0.8 to 2.0. The ...

Effect of the temperature on the TMOS sono-hydrolysis and a study of the structure of the resulting aged sonogels
(Elsevier B.V., 2003-09-01)
The effect of temperature on the oxalic acid catalyzed sono-hydrolysis of tetramethoxysilane (TMOS) was studied by means of a heat flux calorimetric method. The activation energy of the process was measured as (24.5 +/- ...
About the nanoporosity elimination above 800 degrees C in xerogels prepared from TEOS sono-hydrolysis
(Wiley-Blackwell, 2003-04-01)
Small angle X-ray scattering measurements, bulk and skeleton density data and an in-situ study by dilatometric thermal analysis about the nanoporosity elimination above 800 degreesC in TEOS sonogels are presented. Apparently, ...
Structural evolution of aerogels prepared from TEOS sono-hydrolysis upon heat treatment up to 1100 degrees C
(Elsevier B.V., 2003-12-15)
The structural evolution of aerogels prepared from TEOS sono-hydrolysis was studied as a function of the temperature of heat treatment up to 1100 degreesC by means of small angle X-ray scattering (SAXS) and density ...
