Abstract

In this letter, Bi4Ti3O12 (BiT)/TiO2 + SrCO3 (TO+Sr) sol-gel composites were characterized to develop a lead-free, highly sensitive, low-temperature sintering ultrasonic transducer material for nondestructive testing in high-temperature environments. Samples of BiT/TO+Sr and, as a comparison, a 50-μm-thick film of lead-containing material BiT/ Pb(Zr,Ti)O3 (PZT) were fired at 200°C, 400°C, and 650°C, respectively, and their ultrasonic response properties were evaluated from room temperature to 500°C. In the room-temperature performance test, BiT/TO+Sr with specified firing temperature showed higher d33 and sensitivity than BiT/PZT with the same firing temperature. In the high-temperature cycling test, every sample exhibited a stable ultrasonic response up to 500°C. The sensitivity of BiT/TO+Sr is equivalent to that of BiT/PZT. These results indicate that BiT/TO+Sr sol-gel composites, which can be sintered at low temperatures and have high sensitivity, are promising high-temperature piezoelectric materials that can replace the conventional lead-containing material, such as BiT/PZT.
高温测量用bi4ti3o12溶胶-凝胶复合超声换能器
在这封信中,对Bi4Ti3O12 (BiT)/TiO2 + SrCO3 (TO+Sr)溶胶-凝胶复合材料进行了表征,以开发一种无铅、高灵敏度、低温烧结的超声波换能器材料,用于高温环境下的无损检测。分别在200°C、400°C和650°C下烧制BiT/TO+Sr样品和50 μm厚的含铅材料BiT/ Pb(Zr,Ti)O3 (PZT)薄膜,并在室温至500°C范围内对其超声响应性能进行了评价。在室温性能测试中,指定烧成温度的BiT/TO+Sr比相同烧成温度的BiT/PZT表现出更高的d33和灵敏度。在高温循环测试中,每个样品在500°C下都表现出稳定的超声响应。BiT/TO+Sr的灵敏度与BiT/PZT相当。这些结果表明,BiT/TO+Sr溶胶-凝胶复合材料具有低温烧结和高灵敏度的特点,是一种很有前途的高温压电材料,可以取代传统的含铅材料BiT/PZT。
