3.PZT Material


We usually provide P - 41, P - 42, P - 43, P - 51, P - 52, P - 53, P - 81, P - 82, P - 83, PSnN - 5,

PMgN - 51, PZT - 5H, PZT - 5X, PCrN - 4, PliS - 51, PbaS - 4, PbaS - 5, BaTio3.



PZT materials are categorized as functional ceramics. In sensors they make it possible toconvert forces,
pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers
and actuators they convert electric voltages into vibrations or deformations. Piezoelectric materials
are classified according to their chemical composition on the one hand, and by the specific
application conditions on the other.


PZT ceramic is used in a wide variety of applications. Soft (sensor) PZT ceramic powders are typically used
when high coupling and/or high charge
sensitivity are important, such as in flow or level sensors;
ultrasonic nondestructive testing/evaluation (NDT/NDE) applications; or for accurate inspections of automotive,
structural or aerospace products. Material characteristics include
a high dielectric constant; high coupling;
high charge sensitivity; high density with a fine grain structure; a high Curie point; and a clean, noise - free
frequency response.


Hard (high power) PZT ceramic powders are used when high power characteristics are required,
including
applications such as the generation of ultrasonic or high - voltage energy in ultrasonic cleaners,
sonar devices, etc. Important powder characteristics include a high piezoelectric charge constant (d33); a
higher mechanical quality factor that reduces mechanical loss and enables a lower operating temperature; a
low dissipation factor that ensures cooler, more economical operation; high dielectric stability; and low
mechanical loss under demanding conditions.

5. Features


1.High efficiency: high mechanical parameter Q, the transduction efficient between electricity and sound above 95%.
2.High amplitude: the transducer strength is improved by fixing the high speed vibrator directly on the base of washing groove with bolt. Compare with a magnetic expansion vibrator, its amplitude can be improved above 50%.
3. Good heat resistance: a large range of working temperature, low resonance impedance and heat productivity.
4. Good construction: fastened by bolt, easy for assembling, high reliability.
5. The life of more than 5000 hours

6.High electromechanical conversion efficiency


6.Our service
