  • Patent number: 8512606
    Abstract: A procedure for dimensionally accurate sintering of a shaped piece manufactured from a blank of porous ceramic material, in which during the sintering, the shaped piece remains connected via at least one first connection like a rib, with a support that is manufactured from the blank. To ensure with simple procedural steps and simple design measures that the geometry does not change during sintering, the invention provides that the support is manufactured as a section of the blank that at least in sections surrounds the shaped piece by materials removal processing from the blank, and after the manufacture, the support, for one, is connected via the at least one first connection with the shaped piece, and for another, via at least one second connection with the residual blank that in sections is separated from the support.
