When Barium Titanite goes below the curie point, the newly created dipoles will align to create domain regions and these regions will be randomly scattered in all different directions within the dielectric material. The overall net effect is a cancelation of all the dipoles within the material. The process by which Barium Titanite creates dipoles and those dipoles are randomly scattered throughout the dielectric is called spontaneous polarization. When an electric field is applied the dielectric, the titanium ion will shift within the crystal structure and rotate the dipole to align with the electric field. The ability of Barium Titanite to create dipoles and the ability of the dipoles to rotate with the electric field is what gives the material its high permitivity and is why it is called a ferroelectric material. This property means that the permitivity is influenced by temperature, voltage, and time causing capacitance instability.
