Patent number: 7922964Abstract: 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.Type: GrantFiled: August 30, 2002Date of Patent: April 12, 2011Assignee: ItN Nanovation AGInventor: Ralph Nonninger

Patent number: 7582276Abstract: The invention relates to nanoscale rutile or oxide powder that is obtained by producing amorphous TiO2 by mixing an alcoholic solution with a titanium alcoholate and with an aluminum alcohalate and adding water and acid. The amorphous, aluminum-containing TiO2 is isolated by removing the solvent, and is redispersed in water in the presence of a tin salt. Thermal or hydrothermal post-processing yields rutile or oxide that can be redispersed to primary particle size. The n-rutile or the obtained oxide having a primary particle size ranging between 5 and 20 nm can be incorporated into all organic matrices so that they remain transparent. Photocatalytic activity is suppressed by lattice doping with trivalent ions. If the amorphous precursor is redispersed in alcohol, or not isolated, but immediately crystallized, an anatase is obtained that can be redispersed to primary particle size.Type: GrantFiled: August 30, 2002Date of Patent: September 1, 2009Assignee: ITN Nanovation AGInventor: Ralph Nonninger
