Abstract

The study on pore structures of Al-anodized films has generally been made by electron microscopy measurements.
The determination of pore structures by gas adsorption isotherms has widely been utilized as a method useful for quantitative explanation of the character of surface for a large number of materials such as catalysts.
The ethylene adsorption isotherms at -183°C; was applied by Burwell, Sumdsky, and May to the determination of surface areas of aluminum foils which had been aubjected to various etchings and anodic treatments. The results obtained by these investigators corresponded well with those of experiments by electron microscopy.
The surface area was calculated from the B. E. T. equation on the basis of the nitrogen adsorption isotherms at -196°C; for aluminum foils which had been subjected to various anodic treatments. The pore-size distribution curves of aluminum anodized films were determined by the Inkley method.
