Fabrication and Electrical Properties of Lead Zirconate Titanate-Cement-Epoxy Composites

Abstract In this study, epoxy modified lead zirconate titanate-cement 0–3 and 1–3 composites were fabricated via two different techniques with epoxy added as the third phase. The 0–3 composites were fabricated by the normal paste mixing, while the 1–3 composites were fabricated using a dice-and-fill technique. The dielectric and ferroelectric properties of the composites were examined. The results showed that dielectric constant (ϵr) at frequency of 1 kHz of 1–3 composites was higher and dielectric loss was lower than those of the 0–3 composite. The ferroelectric hysteresis loops agree with the results showing reduction area in lossy characteristic and the loops become more apparent in 1–3 composites. The use of epoxy results in a lower Pir value but a reduction in the lossy appearance of P-E loops is observed.
