摘要

研究了x = 0.0625、0.0875和0.100的(Ba0.825+xCa0.175-x)(Ti1-xSnx)O3陶瓷的热释电性能。采用固态反应法制备样品，并定期在红外光下照射至记录的开路电压。当x = 0.0625、0.0875和0.1样品时，开路电压峰值分别为0.8 V、0.70 V和0.53 V。记录了所研究的所有成分的P-E环。利用P-E环数据进一步估算热释电系数。对于x = 0.0625、0.0875和0.1样品，热释电系数分别为5.70 × 10−4C/m2 K、5.5 × 10−4C/m2 K和5 × 10−4C/m2 K。

Pyroelectric performance of (Ba0.825+xCa0.175-x)(Ti1-xSnx)O3 lead free ceramics

Abstract The pyroelectric properties of (Ba0.825+xCa0.175-x)(Ti1-xSnx)O3 ceramics with x = 0.0625, 0.0875 and 0.100 were investigated. Samples were fabricated using solid state reaction route and were exposed to IR lamp periodically to recorded open circuit voltage. Peak value of open circuit voltage was 0.8 V, 0.70 V and 0.53 V for x = 0.0625, 0.0875 and 0.1 samples, respectively. P–E loops were recorded for all the compositions under study. Further pyroelectric coefficient was estimated using P–E loops data. The values of pyroelectric coefficient estimated as 5.70 × 10−4C/m2 K, 5.5 × 10−4C/m2 K and 5 × 10−4C/m2 K for x = 0.0625,0.0875 and 0.1 samples.

期刊介绍： Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals. Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
