Micro-Mechanics of Electrostrictors for Sonar Transducers
Abstract
The higher order electromechanical coupling electrostriction has been proposed as an alternative to the piezoelectric phenomena commonly employed for Navy-type sonar transducers. Based on the results of the parent program Relaxor Ferroelectrics for Electrostrictive Transducers and the three-year AASERT program on the classification of electrostrictors, it was found that the Type I - Pb(B1B2)O3 and Type II - PLZT offered superior overall performance. Specific compositions were selected based on given criteria and fabricated into large ceramic rings. According to Navy requirements, various families of electrostrictive compositions were selected for evaluation as practical Navy transducers, in order to directly compare performance with PZT piezoelectric materials
