Abstract

The ultrasonic transducer is an indispensably critical component for sound velocity measurement. With the increasing demand of high-temperature ultrasonic dual mode transducer applicable to cubic-anvil apparatus, where experiments of high-pressure and high-temperature sound velocity are routinely conducted, a PZT-based ultrasonic dual mode transducer was presented in this study. It was made of a sandwich of two PZT piezoceramic wafers, the upper one generating P-waves and the lower one generating S-waves. The transducer was directly bonded onto a WC anvil of cubic-anvil apparatus using high-temperature adhesive, and then heated in an oven while measuring the bottom echoes from the WC anvil. The results showed that the high-temperature transducer could work up to 140 °C. The transducer features low cost, easy fabricating, and highquality signals, and so we believe it is useful for sound velocity measurement at high temperatures in cubic-anvil apparatus.

基于压电陶瓷的高温超声双模换能器，适用于声速测量仪器

超声换能器是声速测量中不可缺少的关键部件。针对高压、高温声速实验常用的立方砧仪器对高温超声双模换能器的需求日益增加，本研究提出了一种基于压电陶瓷的超声双模换能器。它是由两片PZT压电陶瓷片夹在一起制成的，上面的一块产生纵波，下面的一块产生s波。利用高温胶粘剂将换能器直接粘接在立方砧装置的WC砧上，然后在烤箱中加热，同时测量WC砧的底部回波。结果表明，该换能器工作温度可达140℃。该传感器具有成本低、制作简单、信号质量高的特点，可用于立方砧仪器的高温声速测量。

期刊介绍： High Temperatures – High Pressures (HTHP) is an international journal publishing original peer-reviewed papers devoted to experimental and theoretical studies on thermophysical properties of matter, as well as experimental and modelling solutions for applications where control of thermophysical properties is critical, e.g. additive manufacturing. These studies deal with thermodynamic, thermal, and mechanical behaviour of materials, including transport and radiative properties. The journal provides a platform for disseminating knowledge of thermophysical properties, their measurement, their applications, equipment and techniques. HTHP covers the thermophysical properties of gases, liquids, and solids at all temperatures and under all physical conditions, with special emphasis on matter and applications under extreme conditions, e.g. high temperatures and high pressures. Additionally, HTHP publishes authoritative reviews of advances in thermophysics research, critical compilations of existing data, new technology, and industrial applications, plus book reviews.
