Abstract
The invention relates to a method of manufacturing supports for porous filters. Supports are placed in contact with a first slip coating liquid containing in suspension a mineral powder comprising agglomerates between 10 and 30 microns in diameter, the resulting deposited layer is dried by heating it to approximately 100.degree. C., the layer is brushed so as to remove particles of powder which have not penetrated inside the pores, the thus-treated supports are placed in contact with a second slip coating liquid containing in suspension a mineral powder having a particle size between 1 and 8 microns, and the products obtained are heat-treated at approximately 1500.degree. C. The resulting filters are used for separating isotopes.
