抄録

In order to easily fabricate one directional grain-oriented piezoelectric ceramics with the tungsten bronze structure, the modified rolling-extended orientation method (spin-forming-extended method) was employed. By spin-forming a cylindrical claylike green body, needlelike templates were aligned in the length direction of the green body. The repetition number of the spin-forming process, the content of the templates in the green body and the Pb/Ba ratio in (Pb 1- x Ba x ) 0.96 La 8/3 Nb 2 O 6 used for the templates and matrix powder were optimized. The rectangular ceramics, which are c -axis-oriented in the thickness direction and have a size of 30 mm in the length direction, were consequently obtained.
