| Outline of Final Research Achievements |
Ceramics (polycrystalline materials made from inorganic materials) exhibit electrical properties such as ionic conductivity at high temperatures, in addition to superior physical properties. In ordinary ceramics, the crystalline particles are assembled in random orientations, and the physical and electrical properties of the individual crystalline particles are averaged throughout. When we fabricate polycrystals in which each particle is aligned in one direction, we can expect a remarkable improvement in performance by maximizing the properties of each particle. The researchers prepared crystal-oriented ceramics with high ionic conductivity from two different compounds by heating diffusion couples in air (reactive diffusion method). In addition, a novel crystal-oriented polycrystalline material with lithium-ion conductivity was successfully prepared by combining it with a cation exchange method.
