Abstract:

The crystallographic and dielectric properties of complex perovskites are described in terms of average A- and B-site ionic radii, charges, electronic structures, etc. The relative importance of these to the ferroelectric state is evaluated by a study of a number of solid solutions containing trivalent bismuth. Two new ferroelectrics, Bi0.5K0.5TiO3 and Bi0.5Na0.5TiO3, and the phase diagrams of the systems BixKxBa1-2xTiO3, Bi0.5KxNa0.5-xTiO3, BixKxPb1-2xZrO3, and BixNaxPb1-2xZrO3 are reported. Author
