Abstract

The present 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 present invention provides 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 comprises two or three dimensional ceramic struts that are connected to one another. The cavities in the ceramic struts have a cross-sectional area with a circular or approximately circular or extensively circular or a convex or multiply convex contour. In addition, a method is provided in which a fiber network is produced. The fiber network comprises polymer fibers and/or natural fibers and/or other fibers, with the fibers each having cross-sectional area with a circular or approximately circular or extensively circular or a convex or multiply convex contour. According to the present invention, a ceramic network is utilized while in contact with liquids or gases.
