Effect of Temperature on the Permittivity of Barium Titanate

Abstract

IT is well known1 that the dielectric behaviour of barium titanate and some mixed crystals of it with related compounds is quite different from most other materials (see accompanying illustration). At a certain temperature, θ, a very high value of the permittivity ϵ is found. On the left side of the peak, ϵ decreases with decreasing temperature though still some secondary maxima are found ; on the high-temperature side of the peak, however, ϵ decreases monotonically.
