Description:

This “hard” lead zirconate titanate material was developed for general power applications. Having high electromechanical coupling, high piezoelectric charge constant, and low dielectric loss under high electric driving fields, it is suitable for high power, low frequency broad band projectors, squeeze sensors, spark generators, and other high power electro-acoustic devices.
