PMNT
PMN-PT crystal is a complex perovskite structure solid solution. Curie temperature is 150 ℃. When lead titanate composition ratio is between 0.30 and 0.35, there is a tripartite and quasi-tetragonal phase coexistence phase boundary (MPB). At this time, the piezoelectric constant d33 and electromechanical coupling coefficient k33 can reach up to 2500pC / N and 92% respectively.
It is a very promising piezoelectric material, and can be widely used in surface acoustic wave devices, ultrasound, sonar and other fields.
