Grain oriented ceramics and a production process thereof, as well as an anisotropically-shaped powder and a production process thereof |
摘要 |
<p>Grain oriented ceramics constituted of a polycrystalline body having a first perovskite-type alkali-pentavalent metal oxide compound as the main phase, in which a specific crystal plane of each grain constituting the polycrystalline body is oriented. The grain oriented ceramics are obtained by molding a mixture of a first anisotropically-shaped powder A of which developed plane has a lattice matching with a specific crystal plane of the first perovskite-type alkali-pentavalent metal oxide compound and a first reaction material capable of reacting with the first anisotropically-shaped powder A thereby forming at least the first perovskite-type alkali-pentavalent metal oxide compound such that the first anisotropically-shaped powder A is oriented, and by heating them.</p> |
