A Study on Preparation of Alumina Membranes(1)
The optimum sol solution for making alumina membrane was synthesized by using sol-gel method with aluminium isopropoxide. Two types of supports were made from the $alpha$-Al2O3 powder. The porosities of supports could be controlled by the forming methods and the heat treatment conditions. After the support was coated with optimum sol solution and heat-treated at 50$0^{circ}C$ for 1hour, the thickness of crack-free membrane could be controlled reproductively with dipping time.
