High-temperature piezoceramics

High-temperature piezoceramics

Most competing piezoelectric ceramics (PZT) are limited to 100-125˚C. However, QorTek high-temperature piezoceramics expand this limit to 300-350˚C and can provide solutions to actuation and sensing/harvesting clients with high temperature requirements in a small form factor that enables new design space in actuator and sensing/harvesting applications.

Features

• High curie temperature (Tc>350˚C)
• High strain at high temperature (0.12% at 300˚C)
• Stable properties up to 300°C
• Complex geometries available (cylinders, plates, disks, rings, etc.)

Benefits

• Available in bulk and multilayer formats
• Low drive voltage option
• Enables new design space in actuator and sensing/harvesting applications
• Soft type PZT performance with >2x higher operation temperature
• Proven high temperature harvesting/sensing and actuation capabilities
