METHOD FOR OBTAINING A COLOURED TECHNICAL CERAMIC BODY AND TECHNICAL CERAMIC BODY OBTAINABLE BY SAID METHOD

The invention relates to a method for obtaining a coloured technical ceramic body and a coloured technical ceramic body obtainable by said method.The method of the invention comprising the following steps: providing a composition comprising a technical ceramic material which is zirconia stabilized with yttria, calcia, ceria or magnesia, a first pigment component in an amount between 1 and 10 % by weight related to the total weight of the composition comprising the technical ceramic material and the first pigment component, the composition comprising binder materials, preparing a green body from this composition, debinding the green body, thereafter impregnating the green body with a solution of a further metal-containing pigment component, drying, and sintering the treated green body.The coloured technical ceramic body of the present invention is obtainable by said method and consists of zirconia which is stabilized by yttria, calcia, ceria or magnesia 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 which is formed from the first pigment component and the further metal containing pigment component.
