Patent number: 5180697Abstract: Self-supporting bodies are produced by reactive infiltration of a parent metal into a boron carbide material which may contain one or both of a boron donor material and a carbon donor material. The reactive infiltration typically results in a composite comprising a boron-containing compound, a carbon-containing compound and residual metal, if desired. The mass to be infiltrated may contain one or more inert filters admixed with the boron carbide material, boron-containing compound and/or carbon-containing compound. The relative amounts of reactants and process conditions may be altered or controlled to yield a body containing varying volume percents of ceramic, metal, ratios of one ceramic to another and porosity.Type: GrantFiled: July 12, 1990Date of Patent: January 19, 1993Assignee: Lanxide Technology Company, LPInventors: Terry D.

Patent number: 5163499Abstract: The present invention relates to the formation of a macrocomposite body by spontaneously infiltrating a permeable mass of filler material or a preform with molten matrix metal and bonding the spontaneously infiltrated material to at least one second material such as a ceramic or ceramic containing body and/or a metal or metal containing body. Particularly, an infiltration enhancer and/or infiltration enhancer precursor and/or infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform. Moreover, prior to infiltration, the filler material or preform is placed into contact with at least a portion of a second material such that after infiltration of the filler material or preform, the infiltrated material is bonded to the second material, thereby forming a sealable electronic package.Type: GrantFiled: May 9, 1990Date of Patent: November 17, 1992Assignee: Lanxide Technology Company, LPInventors: Marc S. Newkirk, Danny R. White, Christopher R. Kennedy, Alan S. Nagelberg, Michael K. Aghajanian, Robert J. Wiener, Steven D. Keck, John T. Burke, Peter M. Engelgau, Cheng-Tsin Lee, Michael A. Rocazella
