Mechanistic Study on the Effects of Preparation Parameters on the Structure Property of ZrO2 Aerogels
Abstract:
The mechanism for the effects of titration order, ageing medium and ammonia concentration on the properties of ZrO2 aerogels has been well discussed in the present paper. Different morphologies of ZrO2 aerogels obtained are due to different process of hydrolysis and condensation in different titration order, or to the ageing mechanism in different ageing medium; the effect of ammonia concentration on ZrO2 texture has been related to the free volume of particles and the inhibition to condensation reaction, and ageing process enhances this effect remarkbly.
