Abstract

In this paper a survey is given on ceramic, porous γ-Al₂O₃ membranes. The information of the membranes can be described with a slibcasting model. This means that the layer thickness of the membranes increases linearly with the square root of the dipping time. The pores of these membranes are slit-shaped and the pore size depends on the temperature/time treatment. It amounts 2.7 nm and 4.8 nm at temperatures of 400°C and 800°C respectively while the porosity remains constant in this temperature range (> 50%).

The water permeability is proportional to the pressure drop till at least 50 bar and inversely proportional to the membrane thickness. In ultrafiltration experiments the 'cut off' value of the membrane with 2.7 nm pores is 2000 for polyethylene glycols. The membrane surface can be modified with several types of ions and therefore these types of membranes can be made suitable for gas separation and hyperfiltration applications.
