Abstract

Owing to their exceptional piezoelectric effects, piezoelectric materials play a crucial role in high-end technologies and contribute significantly to the national economy. Bismuth layer-structured ferroelectrics (BLSFs) possess high Curie temperatures, making them a focal point of research in high-temperature piezoelectric sensor devices. However, their poor piezoelectric performance and low direct-current (DC) electrical resistivity hinder their effective deployment in high-temperature applications. To overcome these shortcomings, we employed composition optimization by partially substituting bismuth ions with rare-earth praseodymium ions. This approach enhances the piezoelectric performance and improves the DC electrical resistivity by preventing the loss of volatile bismuth ions and stabilizing the bismuth oxide layer (Bi2O2)2+, thereby reducing the concentration of oxygen vacancies. Consequently, we achieved a large piezoelectric constant d33 of 23.5 pC/N in praseodymium-substituted Bi5Ti3FeO15, which is three times higher than that of pure Bi5Ti3FeO15 (7.1 pC/N), along with a high Curie temperature TC of 778 °C. Additionally, the optimal composition of 4 mol% praseodymium-substituted Bi5Ti3FeO15 exhibits good thermal stability of electromechanical coupling characteristics up to 300 °C. This study holds promise for a wide array of high-temperature piezoelectric applications and has the potential to accelerate the development of high-temperature piezoelectric sensor technologies.

稀土镨取代的 Bi5Ti3FeO15 在高温应用中表现出更强的压电特性
压电材料因其卓越的压电效应,在高端技术领域发挥着重要作用,并为国民经济做出了巨大贡献。铋层结构铁电体(BLSFs)具有很高的居里温度,因此成为高温压电传感器件的研究热点。然而,它们较差的压电性能和较低的直流(DC)电阻率阻碍了它们在高温应用中的有效部署。为了克服这些缺点,我们采用了成分优化方法,用稀土镨离子部分替代铋离子。这种方法通过防止挥发性铋离子的损失和稳定氧化铋层 (Bi2O2)2+,从而降低氧空位的浓度,提高了压电性能并改善了直流电阻率。因此,我们在镨取代的 Bi5Ti3FeO15 中获得了 23.5 pC/N 的较大压电常数 d33,是纯 Bi5Ti3FeO15(7.1 pC/N)的三倍,同时居里温度 TC 也高达 778 ℃。此外,4 mol% 镨取代的 Bi5Ti3FeO15 的最佳成分在 300 ℃ 以下具有良好的热稳定性和机电耦合特性。这项研究为一系列高温压电应用带来了希望,并有可能加速高温压电传感器技术的发展。
