High-Performance Piezoelectric Single Crystals

Unmatched Sensitivity and Energy Conversion for Next-Generation Ultrasonic Systems

PMN-PT and PIN-PMN-PT single crystals represent the most advanced piezoelectric materials available today, delivering significantly higher electromechanical coupling, piezoelectric response, and strain performance than conventional PZT ceramics.

These exceptional properties enable ultrasonic systems with greater sensitivity, broader bandwidth, higher acoustic output, and improved image resolution. From medical ultrasound and non-destructive testing to underwater acoustics and precision sensing, single crystal technology is redefining the performance limits of piezoelectric devices.

Our single crystal materials are available in a variety of custom geometries, including discs, rings, plates, bars, and precision-machined components to meet the requirements of demanding applications.

Why Choose Our Single Crystals?

PMN-PT single crystals provide ultra-high piezoelectric coefficients and electromechanical coupling factors, enabling superior receiving sensitivity and signal resolution.

Compared with conventional PZT ceramics, single crystal materials deliver broader operating bandwidth and significantly improved acoustic output, resulting in enhanced system performance.

Single crystals exhibit substantially higher strain levels, allowing larger displacement and improved actuator performance while operating at lower electric fields.

PIN-PMN-PT single crystals provide improved coercive field strength and thermal stability, making them suitable for higher-power and more demanding operating environments.
