  • Carbosilane polymer precursors to silicon carbide ceramics
    Patent number: 5153295
    Abstract: Polycarbosilane compositions, which can serve as silicon carbide precursors, are formed by a Grignard coupling reaction of a halomethylcarbosilane followed by reduction using a metal hydride. The polycarbosilane compositions that result have a substantially 1:1 silicon to carbon stoichiometry, are substantially non-cyclic and branched, and comprise the repeat units SiH.sub.3 CH.sub.2 --, --SiH.sub.3 CH.sub.2 --, .dbd.SiHCH.sub.2 --, and .tbd.SiCH.sub.2 --.
    Type: Grant
    Filed: July 20, 1990
    Date of Patent: October 6, 1992
    Assignee: Rensselaer Polytechnic Institute
    Inventors: Christopher K. Whitmarsh, Leonard V. Interrante
  • Fiber-containing composite
    Patent number: 5015540
    Abstract: Fibrous material is coated with boron nitride and a silicon-wettable material, the coated fibrous material is admixed with an infiltration-promoting material which is at least partly elemental carbon and the mixture is formed into a preform which is infiltrated with molten silicon producing a composite containing boron nitride coated fibrous material.
