  • Method for manufacturing glass bodies
    Patent number: 4689066
    Abstract: A method of and arrangements for manufacturing glass bodies, in which the starting material for the glass body, being an anhydrous suspension having a microdispersed solids content, is used to form a porous green body which is subsequently purified and sintered, in which by separating the phases of an anhydrous suspension the green body is formed by means of electrophoresis on a deposition electrode whose shape corresponds to that of the glass body to be produced.
    Type: Grant
    Filed: March 3, 1986
    Date of Patent: August 25, 1987
    Assignee: U.S. Philips Corporation
    Inventors: Rolf Clasen, Wilhelm G. Hermann
  • Method for manufacturing glass bodies
    Patent number: 4684387
    Abstract: A method of and arrangements for manufacturing glass bodies, in which the starting material for the glass body, being a suspension having a microdispersed solids content, is used to form a porous green body which is subsequently purified and sintered, in which, by separating the phases of the suspension in an arrangement in which a pressure difference can be built up, the green body is deposited on a porous membrane whose shape corresponds to that of the glass body to be produced, the pores of the membrane having a diameter in the range from 1 to 500 times the average particle diameter of the solids content of the suspension.
