CERAMIC NETWORK, METHOD FOR THE PRODUCTION AND UTILIZATION THEREOF

WIPO Patent Application WO1999028272

A3

The invention relates to the field of ceramics and to a ceramic network which can, for example, be applied as a deep-bed filter and a method for the production and utilization thereof. The aim of the invention is to provide a ceramic network in which the mechanical stability is improved and/or an application dependent structure can be specifically adjusted. To this end, a ceramic network is provided which is comprised of two or three dimensional ceramic webs that are connected to one another. The cavities in the ceramic webs have a cross-sectional area with a circular or approximately circular or extensively circular or a convex or multiple convex contour. In addition, a method is provided in which a fiber network is produced. The fiber network is comprised of polymer fibers and/or natural fibers and/or other fibers, whereby the fibers each have a cross-sectional area with a circular or approximately circular or extensively circular or a convex or multiple convex contour. According to the invention, a ceramic network is utilized while in contact with liquids and/or gases.
