Sphaerische Metalloxidpartikel mit partikulaeren Oberflaechenerhebungen und Verfahren zu dessen Herstellung sowie deren Verwendung

WO 200216508 A UPAB: 20020815 NOVELTY - Spherical metal oxide particles (I), with particulate protrusions on their surface and a diameter of 5 - 10000 nm, comprise oxide(s) of main group I-V, transition, lanthanide and/or actinide metal(s). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the production of metal oxide particles (I). USE - (I) are used for the production of bulk materials, coatings, films, fibers, optical, electrooptical or optoelectronic components, in chromatography, as fillers, as carriers for pharmacological agents, in bioanalysis, in catalysis and sensor technology or in medical or dental technology (all claimed). They are also useful as precursors for producing nanostructurized materials, e.g. ceramics, and coatings with sensor properties. ADVANTAGE - (I) have a 'hedgehog' structure, a larger surface area than usual and form effective bonds in various matrices, e.g. polymers
