摘要： The present invention overcomes the problems caused by certain intergranular phases present during hot pressing. The invention provides a method of removing such problematic intergranular phases while avoiding problems of non-uniformity. In one aspect, the invention encompasses an improvement in a method of sintering a green body by hot pressing, where the green body contains ceramic grains to be sintered and material capable of existing as intergranular phase material during sintering. The improvement embraces hot pressing the body in the presence of a permeable material adapted to receive at least a portion of intergranular phase material as the sintering takes place or after the sintering has been completed.

摘要： The invention relates to a method for producing a ceramic crucible. The following steps are proposed: providing a solidifiable slip, providing a casting mould (10) for the ceramic crucible, pouring the slip into the casting mould, solidifying the slip in the casting mould by (a) freezing and/or (b) changing its pH value, such that a preform is obtained, and heat-treating the preform, such that a ceramic crucible is obtained. The invention additionally relates to a ceramic crucible producible using such a method and a kit for producing such a ceramic crucible, having: (a) a casting mould, preferably a metal mould, for a ceramic crucible, (b) a sol, preferably an aqueous SiO2 sol, comprising a ceramic nanoparticle fraction, (c) ceramic particles comprising a microceramic fraction, (d) optionally a metal powder consisting essentially of metals and/or alloys and/or intermetallic compounds, (e) optionally one or more further additives and optionally organic or inorganic binders. Finally, the invention relates to an apparatus for performing the stated method.
