  • Castable receiver
    Patent number: 4548381
    Abstract: A receiver for casting molten material formed by the steps comprising forming a mixture comprising particulate ceramic powders and a binder; adding the mixture to a mold disposed to form board-like members and hardening the mixture; removing the hardened mixture from the mold; reducing the permeability of the board-like members, cementing the board-like members together to form a receiver and coating the receiver with release agents. Specifically, the receivers are used in the casting of high purity silicon for solar energy cells.
    Type: Grant
    Filed: September 5, 1984
    Date of Patent: October 22, 1985
    Assignee: Solarex Corporation
    Inventors: Curtis P. Mabie, Jr., Robert L. Busby, James A. Cliber
  • Dental material
    Patent number: 4431451
    Abstract: Dentures, dental glazes or coatings, reconstructive jacket-crowns and inlays and restorative constructions over metal or preformed alumina substrates are fabricated from a dental porcelain frit prepared by a gel route.
    Type: Grant

  • Method for preparing microporous glassy filler grains for dental resin composites
    Patent number: 4306913
    Abstract: A microporous filler for dental composite resin restorations has been developed which gives greatly improved finishability, system non-toxicity and x-ray opacification. These fillers are prepared from frits obtained by the low temperature calcination of gelled inorganic "polymers" followed by a pulsed high-heat treatment.
    Type: Grant

  • Additive composition for making dental materials
    Patent number: 4227937
    Abstract: Addition of ammonium stabilized colloidal silica, borax and boric acid to the distilled water in which dental porcelain is fired greatly increases the firing range by reducing "balling" or edge rounding, and flow deformation. Greatly increased machinability and indefinitely prolonged green-biscuit strength is also obtained by the use of the present additive without deleterious effects on the porcelain.
