Title:
HOMOGENEOUS MASSIVE POROUS CERAMIC MATERIAL
Document Type and Number:
WIPO Patent Application WO1999048840
Kind Code:
A9
Abstract:
The invention concerns a homogeneous massive porous ceramic material whereof the mean pore diameter D50 is less than 4 mu m and whereof the sealed porosity is less than 2 %. The material is characterised in that it has a bubble point corresponding to the pore diameter measured on said material. The invention also concerns a hollow fibre based on said material and a module comprising said fibres. Finally the invention concerns a method for preparing said material, and a precursor paste of said material, said paste comprising a pore-forming agent.
