摘要：

The mechanism of the sol-gel phase transition was studied by examination of the change with time and at several temperatures of the apparent viscosity, measured at high shear rates, of acid silicic sols of various concentrations and at pH ranging from 6 to 10, the region where this transition appears. This rheological study has shown the two stages of the sol-gel phase transition and indicated a physical parameter suitable to characterize each stage; an interpretation of the change of the system over a period of time towards the equilibrium state has been proposed.
