摘　　要：为研究中空纤维陶瓷膜结构的形成和过程控制方法,采用相转化与高温烧结技术制备了氧化铝中空纤维陶瓷膜,研究了内冷凝浴、空气距长与氧化铝多孔中空纤维陶瓷膜结构形成的关系.运用扫描电子显微镜(SEM)对膜体横截面和内外表面的微观形貌进行了研究.实验结果表明,可以通过不同内冷凝浴调控氧化铝中空纤维陶瓷膜横截面指状孔的形成方向和厚度;随着空气距的增长,氧化铝中空纤维陶瓷膜的海绵孔层随之增厚.To study the formation of the structure of hollow fiber ceramic membrane and the method of process control, Al2O3 hollow fiber ceramic membrane was prepared by the phase-inversion and sintering technique, its structers spun with different internal coagulant and air-gap had been researched. The microstructure of cross-section, inner edge and outer edge of the membranes was investigated using SEM measurements. The result indicates that the control over direction and thickness of finger-like voids of Al2O3 hollow fiber ceramic membrane was achieved by using different internal coagulant; the thickness of the sponge-like voids increased with the increase in air-gap.
