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

本论文利用溶胶-凝胶法合成勃姆石及其热相变体复合陶瓷膜。

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.

首先，在以异丙醇铝为原料采用Sol-Gel法制备不对称氧化铝膜的过程中，提出用溶解度较大的苯与异丙醇组成的混合溶剂作为分散剂来配制Boehmite溶胶，并且对各环节的控制条件进行了优化。

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〓.

经热处理后不同化学组成的复合陶瓷膜由无定形态或者无定形态和γ-Al〓O〓组成，具有莫来石化学成分的复合膜随着烧结温度的升高，其组成分别为无定形态和勃姆石（200℃）、无定形态和γ-Al〓O〓（400-1000℃），并在1100℃时析出莫来石和α-Al〓O〓。
