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.
