  • Publication number: 20090017200
    Abstract: A method for producing a ceramic coating of metallic and/or ceramic surfaces and products in reactors, process plants and combustion plants includes applying a mixture of fine-particle boron nitride, at least one inorganic binding agent of medium particle size in the nanometer range, containing substantially Al2O3, AlO(OH), ZrO2, Y—ZrO2, TiO2, Fe2O3 and/or SnO2 or an associated precursor compound and at least one solvent and/or water onto a metallic and/or ceramic surfaces or product, and burning the applied mixture into a coating through heating.

  • 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.

  • Patent number: 6533966
    Abstract: Suspensions and powders based on indium tin oxide are prepared by a method in which indium tin oxide precursors are precipitated from solutions in one or more solvents in the presence of one or more surface-modifying components, the solvent(s) are removed from the precipitate, which is then calcined, one or more surface-modifying components and one or more solvents are added, the mixture is comminuted or dispersed to form a suspension, and the liquid components are separated from the suspension to give a powder. The powder may be converted into a moulding by a shaping process. The materials prepared by this method are especially suitable as coating materials for use in microelectronics and optoelectronics.
