Piezoelectric Ceramics Material Selection Matrix
Hard Piezo Ceramic
High coercive field, recommended for medium-power ultrasonic transducers and sonar emitters.
Ultra High-Power Ceramic
Lowest dielectric loss (<0.2%) under intense drive. Standard choice for 20-40kHz heavy ultrasonic cleaning.
Soft Piezo Ceramic
Ultra-high dielectric permittivity (>3200) and d33 coefficient (>590pC/N). Designed for hydrophones and micro-actuators.
