Effect of ionic radii on the Curie temperature in Ba(1-x-y)Sr(x)Ca(y)TiO(3) compounds

A series of Ba(1-x-y)Sr(x)Ca(y)TiO(3) compounds were prepared with varying average ionic radii and cation disorder on A-site. All samples showed typical ferroelectric behavior. A simple empirical equation correlated Curie temperature, T(C), with the values of ionic radii of A-site cations. This corr...

description A series of Ba(1-x-y)Sr(x)Ca(y)TiO(3) compounds were prepared with varying average ionic radii and cation disorder on A-site. All samples showed typical ferroelectric behavior. A simple empirical equation correlated Curie temperature, T(C), with the values of ionic radii of A-site cations. This correlation was related to the distortion of TiO(6) octahedra observed during neutron diffraction studies. The equation was used for the selection of compounds with predetermined values of T(C). The effects of A-site ionic radii on the temperatures of phase transitions in Ba(1-x-y)Sr(x)Ca(y)TiO(3) were discussed.
