Rheological Study of the Sol–Gel Transition in Silica Alkoxides

Reaction-induced phase separation of bis(triethoxysilyl)ethane upon sol–gel polymerization in acidic conditions

“…Similar power law dependence was reported for the tetramethoxysilane-water-methanol system under basic conditions [48]. In this case A = 6900 s and a = À3.2.…”

Physico-chemical control of sol–gel transition of titanium alkoxide-based materials studied by rheology

“…The concentration dependence of the gelation time has also been studied in silica alkoxides [47]. In this case, the exponent was found to be around 3.2.…”

Effect of APC addition on stability of nanosize precursors in sol–gel processing of SiC nanopowder

“…The gelation time has been determined from the variation of the elastic loss moduli with time at different frequencies. Investigations are made for different water amounts, monomer concentrations, and different temperatures [15]. To increase the precision of viscosity measurements Adamczyk et al chose the capillary measurement technique using a new homemade apparatus, largely eliminating suspension sedimentation effects.…”
