| Abstract: | The perovskite phase relaxor ferroelectric single crystals (1 - x) A(B'B")O3-xPbTiO3 exhibit excellent piezoelectric and electrostrictive properties superior to that of the conventional PZT piezoelectric ceramies. The single crystals are used in medical ultrasonic transducer, sonar and solid actuators. Progress in crystal growth and properties of the novel relaxor ferroelectric single crystals, such as Pb(Zn1/3Nb2/3)O3-PbTiO3(PZNT), Pb(Mg1/3 Nb2/3 )O3-PbTiO3 (PMNT) , were reviewed. Medical ultrasonic transducers fabricated by PZNT and PMNT single crystals were introduced briefly. |
