摘要: In order to easily fabricate one directional grain-oriented piezoelectric ceramics with the tungsten bronze structure, modified rolling-extended orientation method (spin-forming-extended method) was employed. By spin-forming a cylindrical claylike green body, needlelike templates were aligned in length direction of body. The repetition number process, content body and Pb/Ba ratio (Pb1-xBax)0.96La8/3Nb2O6 used for matrix powder optimized. rectangular ceramics, which are c-axis-oriented thickness have size 30 mm direction, consequently obtained.
