The present invention addresses the problem of newly providing an oxidation-induced highly-functional self-healing ceramic composition, a method for producing the ceramic composition, a use of the ceramic composition and a method for achieving the enhancement of the functionality of the ceramic composition, by focusing on a repairing stage and a remodeling state in a self-healing process and by carrying out elemental and structural designing of an oxidation-induced self-healing ceramic composition for the purpose of speeding up these stages, unlike the conventional oxidation-induced self-healing ceramic compositions which are developed by focusing on an inflammation stage in the self-healing process. According to the present invention, an oxidation-induced self-healing ceramic composition is provided, which comprises a ceramic base material, an oxidation-active non-oxide-type healing agent dispersed in the base material, and a healing activator, wherein the healing agent is a substance capable of generating an oxide upon the contact with external oxygen resulting from the occurrence of cracking of the ceramic composition, and the healing activator is a substance capable of speeding up the diffusion of a substance that is used for controlling the rate of the oxidation reaction of the healing agent. |
