Abstract
A D-E hysteresis loop of ferroelectrics known in the art has a square shape when the ferroelectrics are a BaTiO.sub.3 single crystal. Such ferroelectrics are used as a non-linear dielectric element of, for example a pulse generating device. The non-linear dielectric element according to the present invention consists of a polycrystal, which is mainly composed of BaTiO.sub.3 and has the chemical composition expressed by the formula A.sub.y B.sub.z O.sub.3, wherein the molar ratio of y/z ranges from 0.92 to 0.99. The non-linearity is excellent and the temperature dependence of the A.sub.y B.sub.z O.sub.3 composition is considerably low.
