摘要/Abstract

摘要： PMN-PT压电单晶材料因其优异的性能得到广泛的应用,不同组分的配比含量会对PMN-PT压电单晶的性能产生较大的影响。同时PMN-PT在大功率上的应用快速发展,所提供的材料参数也都是在小信号(1 V)下测试完成的,而不同PT含量对于PMN-PT单晶在大功率应用下的性能的影响尚不明确。本研究基于恒压法搭建了完整的压电材料大功率测试平台,通过对比测试不同PT含量的PMN-PT单晶在大功率电压激励下的性能表现,以10 mm×3 mm×1 mm的PMN-PT单晶为例,探究材料参数变化。结果显示：不同PT含量的PMN-PT单晶在大功率激励下的材料参数变化趋势相同,但变化程度有较大不同,以PT含量为26%的PMN-PT单晶为例,在功率达到8 W时,压电系数d₃₁增加25%,弹性耦合系数$s_11^E$增加13%,机电耦合系数k₃₁增加17%,机械品质因数Q_m下降73%。随着PT含量的增加,PMN-PT材料更易受温度的影响,功率耐受性显著降低,更易达到退极化温度,而导致压电性能消失。基于本工作的研究结果,可以更好的明确PT含量对于PMN-PT单晶在大功率应用下的影响规律,从而为以PMN-PT为敏感元件的传感器或换能器设计提供可靠的数据支持。

Abstract: PMN-PT piezoelectric single crystals are widely utilized due to their outstanding performance, with varying compositions significantly impacting their properties. While the application of PMN-PT in high-power settings is rapidly evolving, material parameters are typically tested under low signal conditions (1 V), and the effects of different PT (PbTiO₃) contents on the performance of PMN-PT single crystals under high-power conditions remain unclear. This study developed a comprehensive high-power testing platform using the constant voltage method to evaluate the performance of PMN-PT single crystals with different PT contents under high-power voltage stimulation. Using crystals sized 10 mm×3 mm×1 mm as examples, this research explored changes in material parameters. The results indicate that while the trend in parameter changes under high-power excitation was consistent across different PT contents, the degree of change varied significantly. For instance, a PMN-PT single crystal with 26% PT content exhibited a 25% increase in the piezoelectric coefficient d₃₁, a 13% increase in the elastic coupling coefficient $s_11^E$, a 17% increase in the electromechanical coupling coefficient k₃₁, and a 73% decrease in the mechanical quality factor Q_m when the power reached 8 W. As the PT content increased, the PMN-PT materials became more susceptible to temperature influences, significantly reducing power tolerance and more readily reaching depolarization temperatures. This led to the loss of piezoelectric performance. Based on the findings of this study, a clearer understanding of the impact of PT content on the performance of PMN-PT single crystals under high-power applications has been established, providing reliable data to support the design of sensors or transducers using PMN-PT as the sensitive element.
