Abstract

This paper discusses the physical-chemical properties of γ-Al2O3 and TiO2 ceramic membranes which have been prepared by sol-gel techniques from alkoxide starting materials. Mean pore size and pore size distributions are examined using N2 sorption analysis. Particle size of sols as measured by in situ quasi-elastic light scattering is compared with SEM analysis of sintered membranes. Crack-free unsupported monoliths with thicknesses up to 120 μm have been prepared of γ-Al2O3. Supported TiO2 membranes have been fabricated with thicknesses up to 0.5 μm. The γAl2O3 membranes are obtained from “particulate” sols, while for TiO2 both “particulate” and “polymeric” sols have been used to produce membranes.
