摘要 | Al2O3 ceramic powder was applied to modify the large pores defects on the surface of the porous metal Ti support, in situ oxidation method was a convenient method to prepare defect free ceramic/Ti composite membranes on this basis. In situ oxidation conditions experimental results show that the best condition for preparing the TiO2-Al2O3/Ti composite membrane is under 800 degrees C for 2 h, and the microstructure and pore sizes of the TiO2-Al2O3/Ti composite membranes are affected obviously. The thickness and composition of the TiO2/Ti composite membranes are determined by SEM and XRD completely. The pore size distribution of the composite membrane is measured by bubble pressure method, the most probable aperture is about 3.12 mu m, while the average pore size of defect free TiO2-Al2O3/Ti is about 3.23 mu m. After ultrasonic treatment, the slight weight change of membranes reveals no observable change, which indicates that TiO2-Al2O3/Ti composite membranes maintain a good stability. |
