Abstract

Selected glass compositions in the Pb5Ge3O11-PbTiO3 (PG-PT) and Pb5Ge3O11-Pb(Zr1/2Ti1/2)O3(PG-PZT) systems were prepared by quenching from the molten state. After different heat treatments, a multiple ferroelectric composite crystallized at low temperatures, PG-PT or PG-PZT. In this paper the results obtained on the dielectric constant, dissipation factor, ferroelectric hysteresis loop, and pyroelectric coefficient of different bulk and thick-film samples of compositions in the PG-PT and PG-PZT ferroelectric glass-ceramic system are presented and discussed.
