Key Advantages
Ultra-High Sensitivity
Boasts exceptional piezoelectric coefficients (d₃₃: 1100–2200 pC/N), enabling efficient conversion between electrical signals and mechanical vibrations. This sensitivity ensures clear detection of weak acoustic echoes—critical for high-resolution medical ultrasound (e.g., fetal imaging) or NDT of small structural defects.
Broad Bandwidth
Supports a wide range of operating frequencies, from low-frequency sonar (kHz) to high-frequency medical ultrasound (MHz). This versatility allows seamless integration into multi-mode systems, such as dual-frequency NDT probes or hybrid ultrasound/Doppler devices.
High Power Output
Delivers strong acoustic energy under high-voltage excitation, making it ideal for long-range underwater applications (e.g.,marine mapping) where signal strength determines detection range.
001 Polarization
Optimized crystallographic orientation enhances piezoelectric response and stability, ensuring consistent performance across temperature variations and mechanical stress—vital for industrial NDT tools or rugged marine equipment.
Dual Configurations for Flexibility
Low Dielectric (28–30% PT): Balances sensitivity and stability with lower dielectric constant (3500–5000) and loss (<0.5%), ideal for high-precision applications like medical ultrasound transducers.
High Dielectric (30–33% PT): Offers higher piezoelectric coefficients (d₃₃: 1600–2200 pC/N) and broader bandwidth, suited for high-power systems like sonar arrays or large-area NDT scanners.
Technical Specifications
Both Low Dielectric (28–30% PT) and High Dielectric (30–33% PT) materials share the same density of 8.1 g/cc and Poisson’s Ratio of 0.32. For mechanical properties, their Elastic Constant (S₃₃ᴱ) is 40×10⁻¹² m²/N and 50×10⁻¹² m²/N respectively, while the Elastic Constant (S₃₃ᴰ) is 8.1×10⁻¹² m²/N for both. In terms of piezoelectric properties, the Piezoelectric Coefficient (d₃₃) ranges from 1100–1600 pC/N for the low dielectric type and 1600–2200 pC/N for the high dielectric type; the Piezoelectric Coefficient (d₃₁) is -600 pC/N and -800 pC/N respectively. The Electromechanical Coupling Factor (K₃₃) is 0.85–0.90 for the low dielectric material and 0.90–0.95 for the high dielectric one. Both materials have a Curie Temperature of 148°C. Regarding electrical properties, the Dielectric Constant is 3500–5000 for the low dielectric type and 4000–6000 for the high dielectric type; the Coercive Field is 3.0 kV/cm and 2.5 kV/cm respectively; and the Loss (tanδ) is <0.5% for the low dielectric material and <0.9% for the high dielectric one.
