New Inorganic Ultrafiltration Membranes: Titania and Zirconia Membranes

Abstract

Destabilization of colloidal solutions permits preparation of titania and zirconia ultrafiltration membranes. In this work, layer thickness, pore diameter as a function of sintering temperature, and water permeability are developed. These membranes have a very good chemical resistance and can be used in all pH ranges in ultrafiltration processes. A comparison between alumina, titania, and zirconia membranes is given.
