摘要

Invention Patent: "PROCESS FOR THE PREPARATION OF A COMPOSITE METALLIC MEMBRANE, THE COMPOSITE METALLIC MEMBRANE BEING PREPARED IN VIEW OF ITS USE". The invention provides a process for preparing a metal composite membrane containing a thin metal membrane with a desired thickness and a metal membrane support with a porous structure, where the metal membrane and the metal membrane support consist of two metals or metal alloys many different. The process is characterized by the fact that a metal membrane precursor is placed in a non-porous precursor of the membrane support, the metal compound is formed between the two precursors, the desired thickness of the metal membrane is adjusted by mechanical work of the metal compound and then the porous structure for the membrane support is produced.
