摘要

The effect of the angle between the vibration direction and the oriented direction on high-power characteristics was investigated for (001)-textured SrBi_2Nb_2O_9 (SBN) ceramics in the longitudinal mode (33 mode). Specimens with their long side formed at angles of 90 and 45° to the (001)-oriented direction were fabricated from a 95%-textured SBN ceramic. Their high-power characteristics were compared with those of a randomly oriented specimen. In the case of the specimen with a 90° angle, the resonant frequency was almost constant during high-vibration-velocity driving. On the other hand, the resonant frequency of the specimen with a 45° angle decreased with increasing vibration velocity as did that of the randomly oriented SBN specimen. Therefore, it is considered that the excellent high-power characteristics of highly textured ceramics depend on the vibration direction for the (001)-textured ceramics. The angle between the vibration direction and the (001)-oriented direction is important in the excellent high-power characteristics of textured SBN ceramics.
