Porous ceramic membranes with their various advantages, such as better thermal, chemical and mechanical resistance, controllable micro-structure and little pollution to our environment, have been attracting much attention in the scientific community recently. With the development of technology, lowering the cost of ceramic membranes and prepare membranes with high permeability, high selectivity is becoming more important. The advances in the past ten years in techniques are reviewed. Finally, prospect of ceramic membranes was predicted.
