| Research Abstract |
Anodically grown aluminum oxide membrane was prepared using the electrolyte composed of sulfosalicylic acid and sulfuric acid by the voltage reduction process after the anodizing, and it has been clarified to have pore diameter of 0.4 〜 0.5 nm in which this pore diameter is equivalent to the chromate ion. Next the effects of vacuum heating for the precise control of pore diameter of anodically grown aluminum oxide membrane and sol-gel coating on the pore wall were examined. The extension of pore diameter was observed in the heating of 1273K and 1473K, whereas the reduction of pore diameter was observed in the heating of 1673K. It was estimated that pore diameter expanded by the densification of the cell structure caused by the dehydration in the heating of 1273K and 1473K, and it reduced by the sintering of the cell structure in the heating of 1673K. Furthermore, reduction of the nano order of pore diameter and decrease in the pore size distribution were confirmed, when the sol-gel coating was performed.
