| description | The invention relates to a method for producing ceramic hollow fibers from nanoscale particles and to hollow fibers produced in such a manner. The inventive method is characterized in that the ceramic material has a solids content of >25% by volume, preferably >30% by volume and is processed by means of extrusion and spinning. The hollow fiber is sintered according to conventional sintering methods. A hollow fiber produced in this manner is used for metal, polymer and ceramic matrix reinforcements, for artificial organs, for microsystems technology components, for fiber optical waveguides, for ceramic membranes, for solid electrolyte in fuel cells (SOFC), for tissue engineering and for producing extremely light ceramic parts, such as heat shields or brake systems, that are subjected to temperature stresses. The inventive ceramic batch can also be processed by means of silk screening whereby resulting in the production of filigree structures over the ceramic silk screening. |
