摘要：

A new family of polymer-free ceramic piezocomposites with properties combining better parameters of PZT, PN type ceramics and 1-3 composites for wide-band ultrasonic transducer applications is presented. New "damped by scattering" ceramic piezoeomposites were developed based on the original microstructural designing concept and characterized by previously unachievable low Q(M) (Q'(M)=2-5) combined with high piezoelectric (d(33)=250-350) and electromechanical (k(t) =0.45-0.5) parameters, high Curie point (340 degrees C), low acoustic impedance (15-20 MRayl) in a wide working frequency range (0.2-12 MHz).
