A homogeneous bulky porous ceramic material is provided, the average pore diameter D50 of which is less than 4 &#x3bc;m and the closed porosity of which is less than 2 &#x3bc;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.

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.

A multi-channel porous ceramic fiber is provided, preferably having a particular geometry, together with a filtration and/or reaction module comprising such fibers and a precursor paste for the fiber comprising a compression binder as the extrusion binder.
