  • CHEMOMECHANICAL MANUFACTURE OF FUNCTIONAL COLLOIDS
    Publication number: 20110288183
    Abstract: A method for producing a functional colloid during which particles are reactively fragmented in a mechanical manner in a dispersant in the presence of a modifying agent so that the modifying agent is chemically bound, at least in part, to the fragmented colloid particles.
    Type: Application
    Filed: June 9, 2011
    Publication date: November 24, 2011
    Applicant: BUEHLER PARTEC GMBH
    Inventors: Jens Adam, Kai Gossmann, Helmut Schmidt, Karl-Peter Schmitt, Frank Tabellion

  • Nanoscale corundum powders, sintered compacts produced from these powders and method for producing the same
    Patent number: 7022305
    Abstract: Nanoscale corundum powders are obtained by first producing an Al2O3 precursor by adding seed crystals to an aqueous solution of an aluminium compound and adding a base and then converting the Al2O3 precursor into corundum by calcination at a high temperature. Before the calcination, the salts that are present in addition to the Al2O3 precursor are separated off. The resulting product is calcined at temperatures of 700 to 975° C. and any fines that may be present are removed. The resulting corundum powders can be sintered at temperatures of ?1200° C. to produce compacts or components of multiple layer systems.
