摘要：
The present invention relates to a monolithic ceramic body having a mixed-oxide marginal region and a metallic surface, the ceramic body comprising the oxide of a first metal (I), a mixed-oxide marginal region which comprises the oxide of the first metal (I) and the oxide of a further metal (II) having a high affinity for oxygen, and a metallic surface comprising the metal (II) on the mixed-oxide marginal region, the mixed-oxide marginal region comprising a continuous concentration gradient of the first metal (I), starting from 100% in the core down to 0% in the transitional region to the metallic surface of the ceramic body, based on the total metal content (I+II), and a continuous concentration gradient of the further metal (II), starting from 0% in the core up to 100% in the transitional region to the metallic surface of the ceramic body, based on the total metal content (I+II), the oxygen concentration in the mixed-oxide marginal region remaining constant, and the monolithic structure of the ceramic body having no phase boundaries.
