Abstract

Abstract: Sonochemistry is an effective method for the initiation or enhancement of the chemical reactions by ultrasound in a wide range of applications. In this study, the efficiency of a sonochemistry transducer, defined as the ratio of ultrasonic power to electrical power, was investigated for different materials and the thicknesses of the vibration plate in the frequency range 22 kHz–2 MHz. The ultrasonic power was measured by calorimetry. To eliminate the influence of reflected waves, the transducer was attached to the side of a cylindrical vessel. The transducer with a stainless steel vibration plate was more efficient than those with vibration plates of acrylonitrile butadiene styrene plastic or chloroprene rubber. The efficiencies of the transducers also increased with decreasing thickness of the vibration plates. Langevin-type transducers were less efficient than the disk-type transducers.
