 Ferroelectric ceramics

Ferroelectric ceramics are a class of dielectric materials that exhibit a spontaneous electric polarization that can be reversed by the application of an external electric field. This property is known as ferroelectricity, which is analogous to ferromagnetism in magnetic materials. The term "ferroelectric" comes from the similarity in behavior to ferromagnetic materials, although the origin of the name does not imply any direct connection to iron.
