ABSTRACT:
In order to achieve, proceeding from the known methods of producing a ceramic component by sintering, in which an oxygenous ceramic powder is introduced into a sintering chamber, heated in there, and dense sintered under application of a halogen-containing sintering auxiliary agent, a simple and inexpensive method in which the oxygen stoichiometry of the sintered component can easily be adjusted to a given value, it is proposed to have the sintering auxiliary agent released from a reservoir separated from the green body at a given sintering temperature, the halogen superficially reacting with the ceramic powder separating oxygen, and the separated oxygen or a defined part of the separated oxygen being caught by way of an oxygen getter.
