Abstract

A process for the production of a ceramic sheet or shaped body from a ceramic suspension by removal of the dispersion agent is described wherein a ceramic suspension is subjected in a mould 2 by means of two plungers 3, 4 forming an anode and a cathode and a source of voltage 5 to pressure and the action of an electric field, the dispersion agent being simultaneously removed via plungers 4 to dehydrate the ceramic suspension. <IMAGE>
