The preparation and characterization of porous tubular ceramic composite microfiltration membranes, using kaolins and calcium carbonates, were reported. The porous gehlenite (2CaO·Al2O3·SiO2) and anorthite (CaO·Al2O3·2SiO2) based ceramics were obtained by a solid state reaction. A ceramic support, sintered at 1250°C, within an average pore size of about 8μm, a porosity of about 47% and a compression...
