Sol–gel processing of silatranes

European Polymer Journal, 2001
Silatrane complexes are organosilicon compounds synthesized by direct reaction of SiO2 and trialkanolamines. Here, we explore their potential as ceramic precursors via the hydrolytic sol–gel processing method. Viscoelastic analysis is used to characterize the gelation behavior of silatranes based on triisopropanolamine, under different hydrolysis ...

Sol-Gel Processed Coatings

1993
The fundamental principles that govern the production of sol-gel coatings are briefly considered. Among sol-gel processed materials, some examples are given of thin films for abrasion-resistant, corrosion-resistant, optical, electrical and other commercial applications.

Kinetics of bicomponent sol-gel processes

Journal of Non-Crystalline Solids, 1992
A kinetic model is presented for the hydrolysis-condensation reaction of bicomponent sol-gel processes. This model is utilized to simulate the effect of different preparative strategies and to predict the effects of the variation of some experimental parameters.

Sol-gel processed BaTiO3

2009
BaTiO3 thin films deposited on pyrex supports by dip-coating technique and powders have been prepared by the sol-gel route from sols containing a mixture of tetraisopropyl orthotitanate, iso propane, barium acetate and glacial acetic acid. The thickness of the films is proportional to the first power of the withdrawal speed. Gelled sols have been dried

Sol–gel processing of hydroxyapatite

Journal of Materials Science, 1998
Hydroxyapatite, a calcium phosphate-based compound with numerous applications in the biological field was synthesized using the sol–gel processing route. The formation of hydroxyapatite and other compounds during the heat-treatment cycle were identified and characterized using thermal analyses and X-ray diffraction together with infrared and Raman ...

Sol-Gel Processing of Silicates

Annual Review of Materials Research, 1985
The sol-gel process is the name applied to any one of a number of processes that involve a solution or sol that undergoes a sol-gel transition. At the transition, the solution or sol becomes a rigid, porous mass through destabilization, precipitation, or supersaturation (1-4). Rather than restrict this classification of processes by attempting an exact

Prospects for sol-gel processes

Journal of Non-Crystalline Solids, 1990
Abstract The ultrastructural control of materials through sol-gel processes offers significant promise for the achievement of reliable performance in glass, glass-ceramics, ceramics and composites. This will be attainable only if the fundamental chemistry of the sol-gel process is understood.

Photoacid catalyzed sol–gel process

Journal of Materials Chemistry, 2005
The hydrolysis of compounds containing alkoxysilyl moieties catalysed by UV-generated protic acids, followed by condensation of in situ generated silanol groups, is proposed as an effective approach to formation of hard, silicate-type materials by a sol–gel process.
