Abstract

This work revealed that the solid solution compounds of Sr _2-xBa_xNb₂O₇ are promising lead-free materials for high-temperature piezoelectric sensor application. These compounds were confirmed as ferroelectric materials with high Curie points (> 900°C) by their piezoelectric activity after poling, ferroelectric domain switching in their P-E hysteresis loops and thermal depoling behavior. The effect of Ba substitution on the structure and properties of Sr _2-xBa_xNb₂O₇ (x < 1.0) was investigated. The solid solution limit of Sr_2-xBa_xNb ₂O₇ was determined by XRD as x < 0.6. The a-, b-, c- axes, and cell volume increase with Ba addition. The textured ceramics of Sr_2-xBa_xNb₂O₇ were prepared for the first time. The highest d₃₃ was measured as 3.6 ± 0.1 pC/N for Sr_1.8Ba_0.2Nb₂O₇.
