How can i choose piezoelectric ceramic material?
How can i choose piezoelectric ceramic material for my project ? Lots of people asked us the key point issue.
Well, let’s see the specification of piezo material first as below:
Then have a look at the explaining :
|number||material type||characteristics usage|
|1||p-41||A modified binary zirconium titanic acid material. Low dielectric loss and mechanical internal friction, a high electro-mechanical coupling factor and piezoelectric modulus. Used in equipment for medical scanning, supersonic cutting, hole drilling, welding, cleaning, surveying and medium and smaller sized sonar applications, etc.|
|2||p-81||A modified binary material. A strong dielectric field, low wastage, high mechanical strength and good electrical parameter stability. Used in the manufacture of equipment for larger sonar applications, large cleaning machinery, high powered supersonic processing, emulsification transducers, etc.|
|3||p-85||A quaternary piezoelectric ceramic material. High dielectrical coefficient and electro-mechanical coupling factor with a high mechanical strength quality. It has been found suitable for use in the manufacture of high efficiency launch ultrasonic transducers.|
|4||p-45||Each of its main characteristics is in the medium range. It has the dual function of both transmitting and receiving, which may be used concurrently. Used in the manufacture of medium power transducers.|
|5||p-43||The piezoelectric factor d33, g33 is high as is the mechanical strength and coefficient. Its performance remains stable after pressurization. Suitable for gas cigarette lighters, liquid gas ignition, shell blasting, high pressure power sources , etc.|
