  • Patent number: 8168113
    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.

  • Publication number: 20110006450
    Abstract: A dental sintering furnace for sintering ceramic dental elements comprises a receiving chamber (10) for receiving the dental element (14) to be sintered. The receiving chamber (10) is surrounded by an electric heating unit (24) for heating the dental elements (14) to a pre-sintering temperature. Further, the receiving chamber (10) is surrounded by an annular microwave conductor (30) designed as a hollow conductor. On an inner wall (46), the microwave conductor comprises a plurality of decoupling slots (48) to decouple the microwaves in the direction of the receiving chamber (10). In a method for sintering ceramic dental elements, all the dental elements are first heated to a pre-sintering temperature by means of the electrical heating unit (24) and then the dental elements (14) heated to the pre-sintering temperature are irradiated by microwave radiation for coupled heating of the dental elements (14) to the sintering temperature.
