摘要:
The invention relates to a body, in particular for the use in a dental application, comprising an oxide ceramic, containing a bulk material containing an oxide ceramic, preferably a zirconium oxide, and at least one coating containing an yttrium oxide and/or cerium oxide stabilised zirconium oxide, wherein the content of the stabilising compound (c [yttrium oxide] , c [cerium oxide] ) within the coating with respect to the zirconium oxide (in mol-%) satisfies the formula c [yttrium oxide] + 0.6 x c [cerium oxide] ‰¥ 4. Furthermore, the invention relates to a method for producing such a body comprising the steps of providing a bulk material containing an oxide ceramic, preferably a zirconium oxide having a tetragonal microstructure as a main phase, and applying at least one coating containing an yttrium oxide and/or cerium oxide stabilised zirconium oxide, wherein the content of the stabilising compound (c [yttrium oxide] , c [cerium oxide] ) within the coating with respect to the zirconium oxide (in mol-%) satisfies the formula c [yttrium oxide] + 0.6 X c [cerium oxide] ‰¥ 4.
