CERAMIC SHEET, METHOD FOR PRODUCING THE SAME, AND METHOD FOR PRODUCING CRYSTALLOGRAPHICALLY-ORIENTED CERAMIC

A ceramic sheet is self-supported and planar and has a thickness of 10 mum or less, wherein a surface of the sheet includes a specific crystal plane, and the number of crystal grains present in the thickness direction of the sheet at any one point is substantially one. Preferably, the aspect ratio o...

More Information
Summary:A ceramic sheet is self-supported and planar and has a thickness of 10 mum or less, wherein a surface of the sheet includes a specific crystal plane, and the number of crystal grains present in the thickness direction of the sheet at any one point is substantially one. Preferably, the aspect ratio of the crystal grains is 3 or more, and the degree of orientation measured by the Lotgering method is 30% or more. The crystal grains may be composed of an oxide represented by general formula ABO3, wherein the A site contains at least one element selected from the group consisting of Li, Na, K, Bi, and Ag, and the B site contains at least one element selected from the group consisting of Nb, Ta, and Ti. The crystal grains may be composed of an oxide having a perovskite structure and an isotropic shape.
