Abstract
Devices for and a method of manufacturing glass bodies, in which a porous green body is formed from the starting material for the glass body, being an aqueous suspension comprising a highly disperse solids content, which green body is then purified and sintered, and deposited by separating the phases of the suspension through electrophoresis, in such a manner that the solids content of the suspension is deposited on a porous deposition membrane having pores whose diameter is smaller than the average particle diameter of the solid particles present in the suspension, said membrane being arranged between the anode and the cathode, and the space between said membrane and the anode being filled with an electrically conducting liquid, a porous auxiliary membrane being arranged between and at a distance from the deposition membrane and the cathode, said auxiliary membrane having pores with a diameter which is smaller than the average particle diameter of the solid particles present in the suspension, and the space between the auxiliary membrane and the cathode being filled with an electrically conducting liquid and/or the electrodes bringing about the electrophoresis being arranged in such a manner with respect to the suspension that the direction of movement of the suspended particles and the gravitational field acting on the particles extend parallel to each other.
