Dense, optionally uniformly porous thin metal foils, strips or tubes - by liquid drawing

Metal is totally enclosed by a glass, quartz or borax sleeve. The formed compound body is heated until it flows plastically, and then reduced by drawing and/or hot rolling. The produced foil, strip ro tube is cooled at such a rate that desired chemical or physical properties are produced. The sleeve may subsequently be removed, if desired. The method has various possible modifications, according to the desired product. Products obtained may be: metallic capillary filters, fuel cells electrodes, razor blades, metal mono-crystalline foils or metal-quartz foils, catalysts, artificial denture components, active and passive electronic components, special purpose magnetic materials, and many others.
