and Usage |
|
P-41 |
Binary
system lead-zirconate-titanate(PZT) modified material. It
has lower dielectric loss and mechanical internal friction,
higher electro-mechanic coupling coefficient, dielectric
constant and piezoelectric coefficient. Mainly used to make
piezoelectric ceramic transducers for medical application,
ultrasonic cutting, drilling, welding, cleaning, probing,
medium- and small-sized sonar. |
|
P-81 |
Binary
system modified material. It features low dielectric loss in
intensive field, great mechanical strength and stable
electrical parameters. It is mainly used to make transducers
for large-sized sonar, large cleaner, capable ultrasonic
processing and emulsification. |
|
P-85 |
Quarternary
system piezoelectric ceramic material. It has not only a
higher dielectric constant and electro-mechanical coupling
coefficient, but also a high mechanical quality factor. So,
it is especially suitable for making transducers for high
power transmissions. |
|
P-45 |
It
has a double behavior of receiving and transmitting. Major
properties are moderate. Used to make medium power
transducers, which can be used for both receiving and
transmitting. |
|
P-43 |
High
piezoelectric coefficient d33, g33,
and high mechanical strength. Performance is stable after
repeated pressurization. Dielectric constant is relatively
large, especially suitable for making gas lighter,
liquefying gas ignition, high-voltage power supply for
artillery shell fuse. |
|
P-51 |
High
sensitivity and excellent time stability. Used for
underwater sound transducer, sensor, accelerometer, pressure
gauge and buzzer. |
|
PMgN-51 |
It
has very high dielectric constant and electro-mechanical
coupling coefficient, and low mechanical quality factor.
Time stability of each parameter is good. Suitable for
microphone/receiver, pickup, electro-acoustics and filter. |
|
PSnN-51 |
Main
parameters are identical to p-51. It features high stability
of Curie temperature. So, it is a highly sensitive
transducer material for high temperature applications. It
can be used in high temperature probing, thickness
measurement, oil well surveying and high temperature flow
meter. |
|
PliS-51 |
It
has higher electro-mechanical coupling coefficient and
moderate dielectric constant, and high sensitivity. It is
suitable for making various receiving-type transducers with
good time stability and high sensitivity. |
|
PT-71 |
Modified
mono system lead-titanate (PT) material with high Curie
temperature and low dielectric constant, especially suitable
for making high frequency resonator, filter, etc. |
|
PT-72 |
Modified
mono system lead-titanate (PT) material with high Curie
temperature and low dielectric constant, especially suitable
for making high frequency resonator, filter, high
temperature probing, etc. |
