Patent ID: 8501082

Claim:
A method for manufacturing a multipart assembly of sintered oxide ceramic material, comprising one first component, which at least partially surrounds one second component, such that detaching the first component from the second component is impossible without destroying the first and/or second component, comprising the steps of: producing a single-part first shaped part and a single-part second shaped part from an oxide ceramic blank, whereby the first shaped part and the second shaped part are enlarged, relative to the first component and the second component, by a scaling factor that compensates for shrinkage during sintering, completely sintering the second shaped part to produce the second component, and assembling the second component with the first shaped part and subsequently sintering them together, wherein as the first shaped part one employs a shaped part with an opening, whose effective cross section after sintering is smaller than the effective cross section of the second component in front of and behind the opening, in an area not contained within the opening; the sintered first shaped part and the sintered second shaped part being movable with respect to each other.
