Beschreibung
Zusammenfassung:	The present invention relates to novel technical ceramic bodies and a method for preparing these technical ceramic bodies. The method of the invention for the production of a coloured technical ceramic body comprises the following steps: providing a composition comprising alumina, at least one pigment component and optionally binder materials, preparing a green body from this composition, optionally debinding the green body, thereafter subjecting the green body to a treatment with a metal-containing preparation as a further pigment component, and sintering the treated green body. The coloured technical ceramic body of the present invention consists of alumina as a technical ceramic material, the technical ceramic body comprising a first coloured area and a second coloured area of a different colour, whereby the first coloured area contains a first pigment component, and the second coloured area contains a second pigment component in combination with the first pigment component.
