采用溶胶－凝胶技术在α－Ａｌ２Ｏ３载体上涂制了ＴｉＯ２、ＳｉＯ２、Ａｌ２Ｏ３等无机膜，对不同形状、不同孔径的α－Ａｌ２Ｏ３载体作了分析，探讨了载体的性能、载体表面的平整程度、载体表面孔的大小及载体与膜的匹配情况等对膜完整性的影响。结果表明，光洁的载体表面，载体表面孔的大小与膜的粒子差一个数量级及载体与膜的性质相匹配时易获得完整无开裂的膜。
The inorganic films of TiO2, SiO2 and Al2O3 were coated on the α-Al2O3 carrier by sol-gel technique. The α-Al2O3 carriers with different shapes and pore sizes were analyzed. The properties of the carrier, the flatness of the carrier surface, , The size of the surface of the carrier surface and the matching of the carrier and the membrane on the integrity of the membrane. The results show that a clear and crack-free film is easily obtained when the smooth surface of the support, the size of the surface pores of the support and the particles of the support are an order of magnitude different and the properties of the support and the membrane match.
