Piezoceramic Materials

A wide selection of high quality Lead Zirconate Titanate (Piezo) materials are offered to suit many applications. Discs, Plates, Tubes, Rings and Shear Plates in a variety of standard and custom form factors are available from the following materials (please ask for special data sheets):

PIC 140
PIC 140 piezoceramic material offers high mechanical stability and polarization resistance in combination with a high mechanical Q and high Curie Point. Applications are in the field of power ultrasonics, sound navigation and ranging or medical diagnostics.

PIC 141
PIC 141 piezoceramic material offers high electromechanical coupling factors with reasonable mechanical Q, good mechanical stability, and resistance to high electrical fields.

PIC 151
PIC 151 piezoceramic material offers the highest piezoelectric coupling factor and very high dielectric and piezoelectric constants. It is especially suited for micropositioning components, low-frequency ultrasonic transducers, buzzers and ultrasonic speakers.

PIC 155/PIC 255
PIC 155/PIC 255 piezoceramic material offers a high piezoelectric coupling factor, low mechanical Q and minimal response of the dielectric constants to temperature changes. The material is especially suited for low-frequency ultrasonic transducers in pulse mode, for transmission and reception over a wide temperature range and special actuator applications.
