Abstract:
A process for the preparation of a ceramic molded part from a suspension/dispersion with a solids content and a fluid content by depositing solids content at the periphery of a porous self-supporting support that is at least partially immersed in the suspension/dispersion and has the same shape as the molded part to be prepared, but with a reduced size, wherein: the solids content contains oxide-ceramic particles; the porous self-supporting support is detachably connected with a discharge in a zone that is not immersed in the suspension/dispersion; the suspension/dispersion is moved towards the porous self-supporting support by means of a positive pressure difference between a pressure prevailing in the suspension/dispersion and a pressure prevailing in the discharge; wherein the fluid content of the suspension/dispersion enters in the porous self-supporting support with depositing solids content at the periphery of the porous self-supporting support.
