Abstract
Several types of ceramic membranes have been developed for a half of century. Alumina is the most extensive advantage among different type of ceramic membranes. Many types of alumina powder with difference particle size distributions were used as a starting material for extrusion process. The ceramic dough compositions for extrusion were studied. The sheet of alumina supports were fired at various sintering temperatures contained approximately 40% porosity after sintering at 1400℃ for 2 hour.
