PROBLEM TO BE SOLVED: To obtain a ceramic nano composite crystal substance excellent in mechanical characteristics such as strength and toughness by highly controlling the particle diameters and crystalline state of a different kind of substance dispersed in particles constituting the polycrystalline substance and in the boundaries of the particles. SOLUTION: This ceramic nano composite crystal substance in which a different kind of substance is dispersed in the particles constituting the polycrystalline substance and in the boundaries of the particles. Therein, the different kind substance nano particles having particle diameters of <60nm and the different kind substance meso particles having particle diameters of 60-500nm are dispersed in the particles. The different kind meso particles having particle diameters of <500nm and the different kind substance micro particles having particle diameters of <500nm are dispersed in the boundaries. And, the nano particles dispersed in the particles do not exhibit the characteristic lattice distance of the substance, has a lattice distance of 0.8 to 1.2 times the lattice distance of the matrix, and are bound parallel to the lattice planes of the matrix. |
