Ion polarization
As ion polarization (also atom polarization ) the displacement of the relative position of the positive becomes negative ions within an ionic lattice , respectively.
When an electric field acts on a dielectric , the position of the ions in relation to each other within the neutral molecules is changed - provided that ion bonds are contained in the material . Characterized forms a polarization , which is referred to as ion polarization and a special form of displacement polarization is.
If the molecules of the dielectric already have a permanent dipole moment without an electric field , one speaks of orientation polarization .
