The monolithic ceramic body comprises a mixed-oxide marginal region, which comprises an oxide of a first metal and an oxide of a further metal having a high affinity for oxygen, a metallic surface, layers made of further metals, and biocompatible and/or bioactive coatings. The metallic surface comprises the further metal on the marginal region. The mixed-oxide marginal region comprises a continuous concentration gradient of the first metal, 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. The monolithic ceramic body comprises a mixed-oxide marginal region, which comprises an oxide of a first metal and an oxide of a further metal having a high affinity for oxygen, a metallic surface, layers made of further metals, and biocompatible and/or bioactive coatings. The metallic surface comprises the further metal on the marginal region. The mixed-oxide marginal region comprises: a continuous concentration gradient of the first metal, 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； and a continuous concentration gradient of the further metal, 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. The oxygen concentration in the mixed-oxide marginal region remains constant, and the monolithic structure of the ceramic body has no phase boundaries. The further metal is biocompatible. A marginal zone of the ceramic body comprises the mixed oxide-marginal region, and the metallic surface on the marginal region exhibits a thickness of 0.05-140 mu m. An independent claim is included for a method of producing a ceramic body with a mixed oxide-marginal region.본 발명은 혼합 산화물 경계영역 및 금속 표면을 갖는 모놀리식 세라믹 바디에 관한 것으로서； 여기서 상기 세라믹 바디는 첫번째 금속(I)의 산화물, 산소에 대한 높은 친화성을 갖는 다른 금속(II)의 산화물 및 첫번째 금속 (I)의 산화물을 포함하는
