In the present thesis the boehmite and 〓 composite membranes are prepared by sol-gel process.

本論文利用溶膠-凝膠法合成勃姆石及其熱相變體復(fù)合陶瓷膜。

Firstly, A mixing solvent composed of benzene and isopropanol was used to prepare boehmite sols in the Sol-Gel processes during the preparation of asymmetric alumina membranes taking aluminum isoproxide as raw materials. And the operation conditions in relative periods were optimized.

The composite membranes with different ratio of Al〓O〓 to SiO〓 are composed of amorphous matter or amorphous matter and γ-Al〓O〓 when sintered at 600℃. The composite membrane with mullite composition go thrsought the following phase transition as the temperature rising from 200℃ to 1100℃: amorphous matter and boehmite (200℃)→amorphous matter and γ-Al〓O〓(4001000℃)→mullite and α-Al〓O〓.
