Piezo Technologies’ K-181 is a modified lead zirconate titanate piezoelectric ceramic material similar to K-180, but with a slightly lower dielectric constant. This material has a high shear coupling coefficient with low permittivity, and high temperature stability.
This material can be used in high frequency shear resonance applications such as ultrasonic delay lines. Also the high “kt” makes this material usable in some medium range frequency small diameter transducer applications.
