Piezoelectric Single Crystal
PMN-PT
|
JFE MINERAL
CO.,Ltd. has developed a manufacturing technique
for a high-function piezoelectric single crystal
material, which features the piezoelectric constant
that is more than two and a half times larger than
that of conventional products.
●Product Properties
| １ |
Piezoelectric
constant (d33)
is more than two and a half times larger than
the piezoelectric ceramic PZT. |
| 2 |
Electro-Mecanical
(E/M) coupling coefficients (k33)
exceeds 90 percent. |
| 3 |
Acoustic
impedance Z33 is lower than that of the piezoelectric
ceramic PZT and close to that of the human body. |
| 4 |
As
the case of Mn-Zn Ferrite Single Crystals,PMN-PT
single crystals are grown by Melt-Bridgman Method
Accodingly. |
●Applications
・Medical ultrasonic probes
・Non-destructive testing (NDT) vibrators
・Micro actuators
