  • Method for producing a precursor ceramic
    Patent number: 7708934
    Abstract: In a method for manufacturing a precursor ceramic by pyrolysis of elementorganic precursor polymers, carbon nanotubes are bonded to the precursor ceramic and the bonding is performed in such a way that the quantity of free carbon forming in the decomposition of the elementorganic precursor polymers is adjusted in such a way that there is a stoichiometric or moderately hypostoichiometric carbon concentration in the precursor ceramic.
    Type: Grant
    Filed: May 12, 2004
    Date of Patent: May 4, 2010
    Assignee: Robert Bosch GmbH
    Inventor: Martin Köhne
  • Method for Making A Glow Element, A Spark Element, or A Heating Element for A Combustion Device and/or A Heating Device, and Device Thereof
    Publication number: 20090302021
    Abstract: A method for making a glow element, a spark element, or a heating element for combustion and/or heating devices, in particular a glow plug, a spark plug, or a heater, having a corrosion-protective coating for parts of the glow element, spark element, or heating element having a silicon-containing ceramic, and the element thereof. The corrosion-protective coating is composed of a mixture of SiO2 and at least one other substance.
