Sealing of ceramic substances by means of electromagnetic centimetre waves, and receptacle for carrying out the investive method

摘要

A method for manufacturing ceramic parts with a certain porosity by sintering using microwaves, the materials to be sintered being arranged in a vessel, wherein the microwaves introduce sintering energy into the materials to be sintered via electromagnetic waves in the range of vacuum wavelengths between 5 cm-20 cm in multimode having an electromagnetic power of up to one kilowatt, and besides being built from primary materials for the structure of the vessel, the vessel is built from a secondary material which comprises, in particular, a mixture of or mixed crystals of non-metallic, para-, ferro- or antiferromagnetic materials.
