  • Homogeneous bulky porous ceramic material
    Patent number: 7199067
    Abstract: A homogeneous bulky porous ceramic material is provided, the average pore diameter D50 of which is less than 4 ?m and the closed porosity of which is less than 2 ?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.
    Type: Grant
    Filed: January 10, 2003
    Date of Patent: April 3, 2007
    Assignee: Pall Corporation
