1. Overview of PZT Piezoelectric Ceramics
1.1 Product Brief Introduction
We supply two mainstream PZT piezoelectric components: standard discs and standard rings, made of lead zirconate titanate material. Distinct grades are offered for low-power detection and high-power vibration scenarios. Products are processed with precise electrode fabrication. They serve as core active components for ultrasonic transducers, delivering stable electro-mechanical conversion performance.
1.2 Production Technology
PZT raw powder is formed and high-temperature sintered to obtain dense piezoelectric blanks. Precision grinding is carried out to reach target dimensions, followed by surface metallization for electrode manufacturing. Custom dimensions and electrode patterns are available according to customer drawings to match different ultrasonic equipment.
2. Core Characteristics
2.1 Stable Piezoelectric Conversion
Standard PZT discs feature low impedance and low dielectric loss, maintaining consistent electro-mechanical coupling under continuous signal excitation, ideal for precision signal receiving.
2.2 High Power Endurance
PZT-8 hard-type rings own high coupling factor and high Curie point. It resists heat generation and depolarization under long-time high-power driving.
2.3 Diverse Resonance Frequency Options
Multiple standard resonant frequencies are in stock, covering low-frequency high-power vibration to high-frequency precision detection requirements.
2.4 Flexible Electrode Design
Two mature electrode layouts are available: wrap-around side electrodes for discs and inner & outer ring electrodes for rings, adapting to different transducer assembly structures.
2.5 Reliable Dimension Consistency
Strict dimensional tolerance control ensures interchangeability during mass assembly of ultrasonic transducers.
