Ceramic membranes are made from inorganic materials such as alumina, titania, zirconia oxides or some glassy materials and they are utilized in membrane operations. Ceramic membranes have the combined advantage of high chemical, mechanical and thermal resistance. In comparison with polymeric membranes, they are utilized in separations where aggressive media such as acids and strong solvents are present. They have also excellent thermal stability, which makes them useable in high temperature membrane operations like ultra filtration, gas separation, osmosis, reverse osmosis, electrodialysis & electrophoresis. Ceramic membranes can be either dense or porous like that of polymeric membranes.
