  • Patent number: 4152281
    Abstract: Sodium chloride and/or potassium chloride is added to an aqueous suspension of the oxides of lead, titanium and zirconium and stirred until the suspension converts to a gel which is then heated evaporating the water and melting said chloride in which the oxides dissolve and react precipitating lead zirconate titanate.
    Type: Grant
    Filed: April 17, 1978
    Date of Patent: May 1, 1979
    Assignee: General Electric Company

    Inventors: Ronald H. Arendt, Joseph H. Rosolowski
  • Patent number: 4040849
    Abstract: A polycrystalline silicon body is produced by shaping silicon powder having an average particle size less than 0.2 micron into a green body and sintering the body to a density of at least 60% of the theoretical density of silicon.
    Type: Grant
    Filed: January 6, 1976
    Date of Patent: August 9, 1977
    Assignee: General Electric Company
    Inventors: Charles D. Greskovich, Joseph H. Rosolowski
  • Patent number: 4040848
    Abstract: A polycrystalline silicon body is produced by forming a particulate mixture of silicon powder having an average particle size less than 3 microns and boron in an amount ranging from 0.1% to 5% by weight of the silicon powder, shaping the particulate mixture into a green body and sintering the body to a density of at least 60% of the theoretical density of silicon.
