Yuhai PZT materials for High Power Applications

PZT-4 series and PZT-8 Materials offer high mechanical quality factors and low dielectric loss.

High power applications are one of the main uses of [hard" piezoelectric ceramic materials. Piezoelectric materials are categorized as a [soft" material or a [hard" material based on the physical and piezoelectric properties that they exhibit.
High power ceramics are characterized by having larger mechanical quality factors and lower dissipation factors (dielectric loss). High power ceramics produce smaller displacements, relative to soft ceramics but are less susceptible to depolarization from heating under high duty cycles and/or stress. Generally, lower dissipation factors allow the use of hard ceramics in applications that require higher voltages or larger mechanical loads.
Yuhai offers three piezoelectric materials for use in high power applications: PZT-4 series (PZT-41, 42, 43, PZT-8, PCrN-4 and PBaS-4).

PZT-4 series (Navy I Piezo Material)

Yuhai's PZT-4 series piezoelectric material offers the best combination of high power material characteristics and is ideal for use in a variety applications including:

Ultrasonic cleaners
Ultrasonic atomizers
Ultrasonic micro-bonding apparatus
Underwater echo sounders
Sonar devices
High frequency transducers
High stress pressure sensors
Squeeze-type gas ignitors
High power actuators
Vibratory motors
Transformers

PZT-4 series

Yuhai's PZT-4 material offers a relatively high piezoelectric charge constant (d33) when compared to other hard piezoelectric materials therefore producing more power per volume of material. APC 841 exhibits higher mechanical quality factors and a lower mechanical loss permitting a lower operating temperature and a more economical operation. APC 814 performs very well in many transformer applications.

PZT-8 (Navy III Piezo Material)

Yuhai's PZT-8 piezo material is used when the highest electrical drive/duty cycle is required. High dielectric stability and low mechanical loss under high drive conditions make APC 880 an excellent choice for:

Ultrasonic welding
Ultrasonic mixing
Ultrasonic Dispersion
Ultrasonic Surgery
Sonochemistry
Cryogenic SEMs
