High Density / High Performance Piezoceramics

TRS piezoceramic compositions are engineered to produce high density microstructures for improved electrical and mechanical properties. TRS has a variety of standard compositions as well as the capability to develop custom compositions to meet customer requirements.

Advantages of High Density and Fine Grain

• Improved dielectric and piezoelectric properties
• Improved mechanical strength
• Enhanced machinabilty for thin and complex shapes as well as improved production yield
• 30% higher mechanical strength
• Improved dielectric strength

Typical Commercial Uses

• Ultrasound arrays
• Therapeutic ultrasound
• Piezoelectric actuators
• Deformable mirrors
• Sonar
• Vibration sensing
