Abstract
Porous alumina as single tubes and as a multihole structure with controlled properties has been prepared. It is shown that the porous structure of these supports can be controlled without burning out additives but by a variation of the ratio between the main alumina component (α-Al2O3) and aluminium hydroxide (binder) in the extrusion masses and thermal treatment conditions. Gas permeability measurements have been used for the characterization of the supports. The properties of the ceramics are shown to satisfy the requirements of membrane supports.
