Coloured technical ceramic bodies and method for obtaining the same |
摘要 |
The invention relates to coloured ceramic bodies and a method for obtaining these coloured ceramic bodies. The method of the invention comprising the following steps: providing a composition comprising a technical ceramic material, a first 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 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 which is formed from the first pigment component and the further pigment component. |
