Piezoelectric is a kind of can to realize the functional material that mechanical energy and electric energy are mutually changed.Piezoelectric is being pressed
Voltage can occur between both ends of the surface in the masterpiece used time, and this is caused based on piezo-electric effect.Piezo-electric effect refers to that some dielectrics exist
When above being deformed by the effect of external force in a certain direction, polarization phenomena can be produced inside it, while in its two with respect to table
Occurs positive and negative opposite electric charge on face.After external force is removed, it can return to uncharged state again.Piezoelectric is divided into organic
Piezoelectric and inorganic piezoelectric material.Wherein, inorganic piezoelectric material is divided into piezo-electric crystal and piezoelectric ceramics, and piezo-electric crystal is usually
Refer to piezoelectric single crystal, piezoelectric ceramics then refers to piezoelectricity polycrystal.Piezoelectric ceramics refer to mixed with the raw material of necessary composition, into
Type, high temperature sintering, the fine-grain irregular collective obtained by solid phase reaction and sintering process between powder it is many
Crystal.
