Abstract

A method of processing porous metal filters used for separating isotopes of uranium hexafluoride, so as to improve the mechanical strength and resistance to corrosion of the fiters. The filters are placed in the presence of an aluminum-based cement in a closed heat-resistant and oxidation-resistant vessel, the interior of the vessel is disposed in a inert gas atmosphere and the vessel is heated to between 800.degree. and 1,000.degree. C in a furnace for about 1 hour. The filters are used for separating uranium isotopes.
