Abstract
A homogeneous bulky porous ceramic material is provided, the average pore diameter D50 of which is less than 4 &mgr;m and the closed porosity of which is less than 2 &mgr;m, and having a bubble point that matches the pore diameter measured on the material. A hollow fiber based on the material and a module employing such fibers together with a paste constituting a precursor for the material and including a pore-forming agent are also provided.
