Abstract

Ferroelectric powders of PbTiO3 were fabricated and sintered at low-temperatures. The ceramic pores were filled with an epoxy using a vacuum impregnation technique. SEM analysis showed a composite with 3-3 connectivity. The piezoelectric coefficient of the composite was evaluated as (6.0 ± 1.0) x 10-12 m/V by an interferometric technique. The pyroelectric coefficient was 23 µC/m2°C. The pyroelectric detector properties and figures-of-merit of the composite are reported.
