摘要
采用传统固相法制备了Pb(Zr1-xTix)O3 陶瓷,通过调节锆钛摩尔比将其定位于四方区域以改善温度稳定性,并通过优化烧结温度改善电学性能.实验结果表明,当x=0.52时,体系处于四方区域,此时陶瓷的温度稳定性有所提升,在室温～300℃时,d33 变化率为±14.7%.在1 250℃下烧结的Pb(Zr0.48Ti0.52)O3 陶瓷具有最佳的电学性能:压电常数d33=183 pC/N,居里温度TC=402℃,相对介电常数εr=1 209.
Abstract
Pb(Zr1-xTix)O3 ceramics were prepared using the traditional solid-state method.The temperature stability was enhanced by adjusting the zirconium titanium mole ratio to locate these materials within the tetragonal region,and the electrical properties were improved by optimizing the sintering temperature.Experimental results showed that the system entered the monotetragonal region when x=0.52,and the temperature stability of the ce-ramics was subsequently improved.Over the range from room temperature to 300℃,the d33 change rate was±14.7% .The Pb(Zr0.48Ti0.52)O3 ceramics sintered at 1 250℃exhibited optimal electrical properties:d33=183 pC/N,TC=402℃,and εr=1 209.
