Custom Piezoelectric Plate
Material: PZT8, PZT4 or PZT5, Two electrode on the both side or electrode on the same side.
Classified by main composition crystal structure:
The piezoelectric ceramic materials that are now practical are mainly divided into:
One of them is perovskite structure
Ferroelectric and piezoelectric ceramics with a perovskite structure belong to the ABO3 type oxygen octahedron, where A is a monovalent or divalent metal ion, and B is a tetravalent or pentavalent metal.
A positive ions with a larger radius, B positive ions and oxygen ions with a smaller radius are respectively located at the vertex, body center and face center of the unit cell lattice. as the picture shows. This structure can also be seen as a group of BO6 octahedrons arranged in a simple cubic pattern. Each oxygen octahedron is connected by common oxygen ions. A positive ion occupies the gap between the oxygen octahedrons. The perovskite cell It is cubic, and can also be deformed to have triangular and tetragonal symmetry. Ferroelectric ceramics such as barium titanate, lead titanate, lead zirconate titanate and KxNa1-xNbO3 have a perovskite structure.
