PIEZOELECTRIC PROPERTIES OF PB5GE3O11 BONDED PZT COMPOSITES

Pb5Ge3O11 was used to form dense piezoelectric composites with PZT at temperatures below 1000°C. The composite material demonstrated that the ferroelectric component may be stabilized against depoling by an insulating grain boundary phase. Composites prepared using 30% Pb5Ge3O11 almost fully stabilized the polarization against reverse field of 40 kv/cm, with d33 = 65 × 10-12 m/v and k = 470. © 1979.
