Abstract

A new method of PZT/PZT ceramic piezocomposites fabrication is proposed. Different types of PZT type piezoceramics powders and milled PZT piezoceramics particles as well as pre-sintered piezoceramic granules were used as matrix and filling components respectively. Samples of piezocomposites with the volume fraction of components 0-100% were manufactured and tested. Complex sets of elastic, dielectric, and piezoelectric parameters of piezocomposites were measured by impedance spectroscopy method using piezoelectric resonance analysis (PRAP) software. Velocity and attenuation of longitudinal and shear waves for polarized and non-polarized samples were measured by pulse-echo and through-transmit ultrasonic methods.
