Issam A. Khoury 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).

  • Preparation of thin ceramic sheets
    Patent number: 4966742
    Abstract: Thin, free-standing ceramic precursor tapes are prepared from solutions comprising certain coordination complexes, thus eliminating the use of ceramic powders. The precursor tapes can be calcined to form thin ceramic sheets useful in electronic applications.
    Type: Grant
    Filed: August 20, 1985
    Date of Patent: October 30, 1990
    Inventors: Issam A. Khoury, Robert H. Heistand, II, Iwao Kohatsu
  • Melt processable, green, ceramic precursor powder
    Patent number: 4929575
    Abstract: A melt processable, green ceramic precursor powder is prepared from a solution containing a melt processable organic polymer and a polyahl coordination complex. The powder may be melt processed, as in extrusion, hot pressing, or injection molding, to form preceramic greenware useful in electronics applications.
    Type: Grant
    Filed: March 21, 1988
    Date of Patent: May 29, 1990
    Assignee: The Dow Chemical Company
    Inventors: Issam A. Khoury, Horst G. Langer
  • Dispersion process for ceramic green body
    Patent number: 4816072
    Abstract: A process is described for the preparation of a ceramic green body by hydrolyzing at least one alkoxide selected from each of two specified groups to form a dispersion of their reaction product, concentrating the dispersion to a sediment without drying it, and admixing a binder and a plasticizer with the sediment to make a ceramic slip formulation. A release agent can optionally be admixed. The slip formulation is then cast as a ceramic green body. The proportions of alkoxides can be adjusted, as desired, to produce a ceramic green body which is dielectric and useful for microcapacitors or as a conductor.
