This study describes the fabrication of macroporous ceramic supports for membranes prepared from quartz sand and dolomite mixtures, which are abundant local raw materials; tubular supports are made using the extrusion technique. The structure was ana
Ceramic based materials covered with a mixture of mullite and zircon on the top, strengthened by the addition of zinc and magnesium compounds at different rates (37 % and 50 %) and made by a co-precipitation method are studied. The thermally treated
