Piezoelectric Materials

High Performance Single Crystal Piezo Material

Morgan Electro Ceramics announces the release of our new single crystal piezoelectric material, PMNT-28, for use in transducer and actuator devices.

The new family of U.S. manufactured materials was formulated to exhibit very large electromechanical coupling coefficients and also offers high dielectric constants and low dielectric losses.

Property PZT-5H PMN-PT-28
k33 0.75 0.86-0.90
k’33 --- 0.85-0.88
kp 0.69 0.86
k31 0.39 0.42
d33 (pC/N) 690 1200-2000
d31 (pC/N) -280 -370
g33 (x10-3 Vm/N) 19.7 15.8
g31 (x10-3 Vm/N) -9.5 -6.8
Y33E (GPa) 4.8 25-30
s33D (x10-12 m2/N) 9 10-14
K3T after poling (@ 1kHz) 3300 4500-6000
D.F. 0.02 <0.01
Qm 70 65
Freq. Const. Nt (Hz-m) 2000 1800
Acous. Imp. (MRayl) 30 28
Density (kg/m3) 7700 8100
TRT Depolarization Temp. (°C) --- 85-100
Curie Temp. (°C) 195 125-140

Applications include high power sonar projectors, medical imaging, and actuators.

The increased coupling and displacement results in improved bandwidth, sensitivity and source level in applications.

Finished elements are available with lateral dimensions up to 1.25” (38 mm).

Electrodes are sputtered thin film nichrome/gold.
