摘要
采用固相合成法在1 125～1 175℃烧结范围内制备了0.15BiScO3-0.85(Pb0.88Bi0.08)(Ti0.97Mn0.03)O3(BSPT-Mn)高温压电陶瓷.所有样品均为纯相,晶粒尺寸分布符合正态规律,掺杂元素均匀,未发现明显的富集现象.研究表明,在1 150℃烧结制备的BSPT-Mn高温压电陶瓷的最大机械品质因数为1 500.3,在484.4℃温度下压电常数为289.8 pC/N,压电性能良好.
Abstract
The 0.15BiScO3-0.85(Pb0.88Bi0.08)(Ti0.97Mn0.03)O3(BSPT-Mn)high-temperature piezoelectric ce-ramics were prepared by traditional solid-state method in the sintering range of 1 125-1 175℃.All samples are pure phase,and the distribution of grain sizes follows the normal distribution pattern.The dopant elements are uni-form and no significant enrichment phenomenon is observed.The results show that the BSPT-Mn high-temperature piezoelectric ceramic prepared by sintering at 1 150℃ achieved a maximum mechanical quality factor of 1 500.3,and exhibited good piezoelectric properties with dielectric constant d33 of 289.8 pC/N at a working temperature of 484.4.
