Wide choice of PZT formulations
High power or "hard" ceramics can withstand high levels of electrical excitation and mechanical stress. These materials are suited for high voltage or high power generators and transducers.
This material range is ideally suited for ultrasonic cleaning, sonar, and other high power acoustic radiation applications. These materials are designated as PZT-4 series type materials and are capable of producing large mechanical drive amplitudes while maintaining low mechanical and dielectric losses. In addition, it can be used under both constant and repetitive conditions.
This material range is used in high power applications, even though its piezoelectric activity level is slightly lower than PZT-4 series types. With an extremely high mechanical quality factor and extremely low loss factor, PZT-8 series materials have the ultimate power handling capability.
