Description

We formed a c-axis-oriented (Sr,Ca)2NaNb5O15 (SCNN) sheets using a rotation magnetic field, and succeeded in realizing a c-axis-oriented SCNN multilayer piezoelectric ceramic (O-MLPC). The Lotgering factor of both the c-axis-oriented SCNN sheet and inner piezoelectric ceramic of the O-MLPC were approximately 0.80 after sintering. The applied voltage dependences of displacement for both the O-MLPC and a conventional multilayer piezoelectric ceramic (MLPC) with randomly oriented ceramics were examined. As a result, we confirmed that the displacement characteristic of the O-MLPC increased up to a value 2.5 times larger than that of the MLPC. (author)
