PIEZOELECTRIC MATERIALS

Lead Zirconate Titanates

Navy Type I –PKI 409
It is designed to serve as a driver where high power and low losses are dictated by design. It is primary well suited for ultrasonic cleaners, fish finders and sonars.

Navy Type II – PKI 509
It is designed for applications that require high electromechanical activity and high dielectric constant. These are used primarily as receivers, e.g. hydrophones, phono pickups, sound detectors, accelerometers, delay lines, flow detectors and flow meters.

Navy Type III –PKI 802, 804 and 809
It is specifically used as a driver that exhibits low losses under extreme driving conditions and has a high Q. These materials are well suited for medical applications.

Navy Type V –PKI 532
It is used as a sensor that requires low impedance, high dielectric constant and high sensitivity.

Navy Type VI –PKI 552 and 556
These materials are used in sensors that require extremely high dielectric constants and large displacements. PKI 556 has been slightly modified to give a higher g33 value, higher k33 and lower loss factor. This formulation aids the design engineers by giving more flexibility with the type VI class of material.

Lead Metaniobates

PKI 100 and 105
They exhibit properties not usually present in other types of piezoelectric ceramics. The noteworthy facts are its low mechanical Q, negligible aging, wide range of operating temperatures, and small values for lateral and planar coupling. The low mechanical Q enhances the use of PKI 100 in the construction of wide bandwidth sensors for high frequency pulse echo measurements that require a short pulse and critical resolution. Its negligible aging helps simplify circuit design. Wide variations in temperature have limited effect on its dielectric and piezoelectric properties, making it ideal for high temperature applications. Its high longitudinal coupling compared to lateral and planar coupling allows it to generate a better response under hydrostatic pressures and makes it useful for underwater sonar equipment.
