| Abstract: | Porous alumina was prepared by anodization in oxalic acid electrolyte. Scanning electron microscope （SEM） was used to observe the surface morphology of porous alumina. Many factors affecting on preparing porous anodic alumina were investigated. According to the experiments, it is shown that the annealing pretreatment, proper oxidation time and oxidation voltage can ensure effectively the quality of porous alumina. The temperature for preparing good porous alumina depends on some parameters including oxalic acid concentration, oxidation voltage etc.. |
