Abstract :
The influence of the various techniques on the character of microstructure and temperature stability of resonance frequency for piezoelectric materials PCR-62 and PCR-63 has been considered. It is noted that temperature stability has high magnitudes at transition from hot pressing to traditional sintering. It is connected with an increase of field of bulk charge when the density of ceramics decreases
