| Abstract: | A new typical piezoelectric single crystal PMNT has the outstanding properties, and will gradually become a replacement of the conventional piezoelectric ceramics, PZT, and can be used for ultrasonic imaging, hydroacustric transducer, high strain actuartors and so on. We surmount a limit of the conventional solvent - assisting method for growing the relaxor fennoeleceric single crystal, now using Bridgman's method, prepare a high-quality and big size crystal PMNT, according to its character, We study its latent application, the results show that single crystal PMNT has a potential applications in piezoelectnic transducers. |
