Samples have been prepared by colloidal suspensions cast on alumina or kaolin substrates. Supported membranes have been characterized by Hg porosimetry, MEV, XRD and N-2 adsorption-desorption isotherms. The results show that the narrower pore size distribution of alumina substrate allowed to prepare membranes more homogeneous and free of cracks than that supported on kaolin. The crystallite and pore sizes of the membranes could be controlled by adjusting the temperature of sintering, allowing materials with adequate microstructure with application for ultrafiltration process.477-481engsupported membraneSnO2 coatingpore size distributionsinteringArtigo10.1007/BF02436885WOS:A1997WQ33400076Acesso restrito997120258528696755842986818708650000-0002-8356-8093
