Support for porous barriers made of baked ceramic material

摘要

The invention relates to a support for a ceramic porous barrier of the kind used for obtaining a concentration of uranium 235 in uranium hexafluoride by ultrafiltration. The support is formed by superposing a number of layers in the form of pastes, the particle size being homogeneous and constant in each layer and decreasing from the outer towards the inner layers. The pastes are prepared from powdered materials such as metals, oxides, silicates, borides, nitrides and halides to which mineral binders are added. The pastes are simultaneously extruded or co-extruded after which the resulting support is baked.
