Abstract

A permeable aluminium membrane for separating gaseous isotopes by gaseous diffusion is characterized by a plurality of permeable spaced portions of aluminium oxide which extend through the thickness of the foil and which are formed by anodic oxidation of the aluminium. Specification 824,594 is referred to.
