According to specialty general knowledge: piezoelectric ceramics just has piezoelectric property after having to pass through polarization.So-called polarization (Poling)
Be exactly on piezoelectric ceramics, add a strong dc electric field, make the electricdomain in piezoelectric ceramics along direction of an electric field orientations, also known as manually
Polarization processes, or poling processes.
Measuring technology shows with theory analysis, and the POLARIZATION MECHANISM of piezoelectric ceramics depends on its internal structure.Piezoelectric ceramics is
Irregularly " inlayed " by many little crystal grain and form.Each little crystal grain can be seen as a little monocrystalline, and its Atom (ion) is all
Being the arrangement of regular (periodically), form lattice, lattice is made up of repetitive one by one i.e. structure cell again.Thus it is called many
Crystal.Structure cell (T ＜ TC) its positive and negative charge center at a certain temperature is misaligned, produces spontaneous polarization Ps, and polarised direction is from negative
Charge-site points to center of positive charge.Crystal grain is the most identical with the lattice direction of crystal grain, in terms of entirety, is still confusion, random
Then.In order to make piezoelectric ceramics be in energy (electrostatic energy and elastic energy) minimum state, crystal grain arises that some zonules,
In each zonule, structure cell spontaneous polarization has identical direction, but the spontaneous polarization direction between adjacent domain is the most different.Spontaneous
The region that polarised direction is consistent is referred to as electricdomain, and monolithic ceramic includes many electricdomains.
The effect that artificial polarization processes, it is simply that the sufficiently high DC electric field that adds on piezoelectric ceramics, and keep certain
Temperature and time, forces its electricdomain to turn to, and forces its spontaneous polarization to align in other words.
Before polarization, there is the electricdomain that many spontaneous polarization directions are different in each crystal grain, the polarization intensity in pottery is zero.Pole
When change processes, crystal grain can form single domain, and spontaneous polarization arranges along outer field direction as far as possible.After polarization processes, external electric field is zero, by
In internal restoring force (such as the release etc. of the internal stress that polarization produces) effect, each crystal grain spontaneous polarization can only be pressed to a certain extent
Former external electric field direction is orientated, and the polarization intensity in pottery is no longer zero.This polarization intensity, referred to as remanent polarization.
As shown in the above description, polarization condition is only under polarized electric field effect, and electricdomain could be along direction of an electric field orientation row
Row, so it is the principal element in polarization condition.Polarized electric field is the highest, and the effect promoting electricdomain to arrange is the biggest, and polarization is more filled
