Piezoelectric Ceramic Powder

As a leading supplier of piezoelectric ceramic raw materials, we empower clients in hydroacoustic detection, smart sensing, and precision actuation through high-performance powders and collaborative innovation, driving cutting-edge advancements in piezoelectric technology.

Structural Design

The powder is based on a lead zirconate titanate (PZT) system, optimized via phase-boundary engineering and doping modification to enhance crystal structure for high electromechanical coupling and low loss.

● Hard Powders: Dense grain boundaries improve mechanical strength.

● Soft Powders: Ion doping enhances lattice flexibility for multilayer monolithic processes and low-temperature sintering (e.g., DCP46, DCP51), enabling complex device fabrication.

Material Properties

● Hard PZT Powder:

 ○Low dielectric loss (tanδ ≤0.8%), high mechanical Q-factor (Qm ≥800), and power durability.

 ○Typical models (DCP42/44/46): Dielectric constant 1200–1380, electromechanical coupling coefficient kp ≥0.59, ideal for high-stability emission.

● Soft PZT Powder:

 ○High dielectric constant (ε33 up to 4500), large piezoelectric strain constant (d33 ≥680×10⁻¹² C/N), and kt ≥0.78 for high displacement/sensitivity.

 ○Typical models (DCP5A/51/5H): Suited for precision actuation and high-sensitivity sensing.

Core Advantages
