A process for the preparation of a mineral, porous, permeable membrane

摘要

The process is characterizes in that one deposit on a porous substrate permeable a thin layer of a gel of hydroxide at least of aluminum peptized, dried the membrane thus obtained, then subjected to a baking at a temperature ranging between 500c and 1100c. / p & & p & application of the membranes obtained has the isotopic separation of gas, a filtration and the ultrafiltration.
