Steven D. Poste has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Ceramic foams
    Patent number: 5441919
    Abstract: Ceramic foams in which the open cells are connected by a three-dimensional, substantially continuous ceramic matrix formed of interconnected hollow ligaments, are made from an open-cell, reticulated precursor metal, i.e. a metal foam. The precursor metal first is treated so as to allow a support coating to form thereon, and thereafter the coated precursor is heated above the melting point of the metal in the presence of an oxidant to form an oxidation reaction product.
    Type: Grant
    Filed: March 21, 1994
    Date of Patent: August 15, 1995
    Assignee: Lanxide Technology Company, LP
    Inventors: Eugene S. Park, Steven D. Poste

  • Production of ceramic and ceramic-metal composite articles incorporating filler materials
    Patent number: 4981632
    Abstract: A method of producing a composite comprising a self-supporting polycrystalline material obtained by oxidation reaction of a molten parent metal with a vapor-phase oxidant comprising infiltrating a filler exhibiting inter-particle pore volume with a parent metal under conditions which control the respective rates of said metal infiltration and said oxidation reaction.
