  • Patent number: 7897197
    Abstract: Disclosed are sintered bodies that include: (a) 30 to 100 mol % of NbOx, wherein 0.5<x<1.5; and (b) 0 to 70 mol % of MgO. The sintered bodies may be used as inert apparatuses in the production of niobium suboxide powder or niobium suboxide anodes, or as chemically resistant components in chemical apparatuses.
    Type: Grant
    Filed: June 13, 2008
    Date of Patent: March 1, 2011
    Assignee: H. C. Starck GmbH
    Inventors: Christoph Schnitter, Gerhard Wötting
  • Patent number: 7754185
    Abstract: The invention relates to high purity MoO2 powder by reduction of ammonium molybdate or molybdenum trioxide using hydrogen as the reducing agent in a rotary or boat furnace. Consolidation of the powder by press/sintering, hot pressing, and/or HIP is used to make discs, slabs, or plates, which are used as sputtering targets. The MoO2 disc, slab, or plate form is sputtered on a substrate using a suitable sputtering method or other physical means to provide a thin film having a desired film thickness. The thin films have properties such as electrical, optical, surface roughness, and uniformity comparable or superior to those of indium-tin oxide (ITO) and zinc-doped ITO in terms of transparency, conductivity, work function, uniformity, and surface roughness.

  • Publication number: 20070071985
    Abstract: The present invention is directed to a composition consisting essentially of: a) from about 0.1 to about 60 mole % of MoO2, b) from 0 to about 99.9 mole % of In2O3, c) from 0 to about 99.9 mole % of SnO2, d) from 0 to about 99.9 mole % of ZnO, e) from 0 to about 99.9 mole % of Al2O3, f) from 0 to about 99.9 mole % of Ga2O3, wherein the sum of components b) through f) is from about 40 to about 99.9 mole %, and wherein the mole %s are based on the total product and wherein the sum of components a) through e) is 100. The invention is also directed to the sintered product of such composition, a sputtering target made from the sintered product and a transparent electroconductive film made from the composition.

  • Patent number: 6916560
    Abstract: The invention relates to a silicone nitride based substrate for semi-conductor components, said substrate containing silicon nitride (Si3N4), silicon carbide (SIC) and silicon oxynitride(Si2N2O) as crystalline phases. The silicon phase content is less or equal to 5%, the shrinkage during production is less than 5% and the open porosity of the substrate is less than 15% vol. %. The invention also relates to a method for the production and use of said substrate as an element of semi-conductor components, particularly thin film solar cells, and semi-conductor components which contain said substrate.
