Piezoelectric Single Crystals PIN-PMN-PT

Product Features

1. World's largest piezoelectric single crystals (80-mm diameter x 300 mmL) enable the production of large products.

2. Significant improvement in consistency in properties throughout the entire crystal due to more uniform crystal structure using our proprietary crystal growth technologies.1)

3. A piezoelectric constant that is over twice that of conventional ceramic piezoelectric materials.

4.The coercive field of the PIN-PMN-PT single crystals is twice that of the PMN-PT single crystals.
