摘要：
The effects of water and catalyst (formic acid) concentrations and temperature on tetraethoxysilane hydrolysis, followed by gel formation, have been studied. The catalyst concentration is found to have a stronger effect on the variation rate of dynamic viscosity of the system compared to the effect of water concentration. The thermal behavior of the thus-prepared xerogels has been studied in an air flow; distinctions have been noticed for samples whose initial dispersion-bound systems were formed at room temperature.
