Electrostrictive Ceramics

TRS developed three PMN-PT compositions for sonar applications. PMN-15, PMN-38, PMN-85 have operating temperature ranges of 0 to 30, 10 to 50, and 75 to 95 ˚C, respectively, and 6 to 10 times the strain energy density of PZT-8. The higher temperature materials have higher coupling coefficients at the temperature of the peak dielectric constant.
