Synthesis and Properties of Ln3Ti2TaO11Mixed-Layer Perovskite-like Compounds
Source abstract
Abstract
The Ln3Ti2TaO11(Ln = La, Pr) compounds (A n B n O3n+ 2family) with noncentrosymmetric layered perovskite-like structures were prepared by heat-treating coprecipitated hydroxides, and their lattice parameters and density were determined. The structural changes accompanying the formation of these compounds were studied. Analysis of x-ray diffraction data indicated that, in the structures of Ln3Ti2TaO11 , the LnTaO4and Ln2Ti2O7perovskite layers are stacked in an ordered manner. The spontaneous polarization in Ln3Ti2TaO11was evaluated.
