Description of piezoelectric ceramic technology
Piezoelectric effect is a property of most materials with asymmetric crystal structure.Quartz and tourmaline, crystalline materials that occur naturally in nature, also have these piezoelectric properties.Artificial synthetic piezoelectric materials include artificial quartz, piezoelectric ceramics, lithium niobium acid, zinc oxide and high polymer piezoelectric film.Another class of materials with these piezoelectric properties is polarized piezoelectric ceramics.Compared with naturally formed piezoelectric crystals, piezoelectric ceramics have crystal structure.The most commonly used piezoelectric ceramics are lead PZT.Compared with single crystal materials, piezoelectric ceramics have many advantages, especially being easy to manufacture in various shapes and sizes.Instead, single crystals must be cut along a certain crystallographic direction, which cannot meet the custom requirements of the customer.
PZT lead piezoelectric ceramics, the crystal structure of the piezoelectric material is the chemical formula of Pb(Zr11xTix)O3 binary piezoelectric ceramics.Piezoelectric ceramics are made up of tiny particles , each containing domains arranged in the polar direction of the cells.Before polarization, the particles and domains are randomly oriented;Therefore, the net pole of the material is zero, that is, the ceramics do not exhibit piezoelectric properties.Applying a sufficiently high DC field (called the polarization process) will Orient the field in the direction of the field and cause residual polarization of the material.
