A NEW DEVELOPMENT OF POLAR GLASS CERAMIC HYDROPHONE FOR THE FREQUENCY RANGE 100-1000 kHz

摘要

This paper firstly describes the piezoelectric properties of the polar glass ceramic, such as piezoelectric constants, electromechanical coupling coefficient, frequency constants, mechanical Q factor,etc. Secondly,the characteristics of hydrophone designed with polar glass ceramic tube are presented. These results show that the polar glass ceramic is a good piezoelectric material for the standard hydrophone in the frequency range 100 -- 1000 kHz.
