Title: Specific Features of the Structure and Properties of High-Temperature Oxide Materials Based on Bismuth Sodium Titanate

Abstract

Single-phase ceramic samples from the region of morphotropic phase boundary in the (1–x)(Na{sub 0.5}Bi{sub 0.5})TiO{sub 3–x}BaTiO{sub 3} and (1–y)[(Na{sub 0.5}Bi{sub 0.5})TiO{sub 3–x}BaTiO{sub 3}]–yBi(Mg{sub 0.5}Ti{sub 0.5})O{sub 3} systems, modified by low-melting LiF and 0.6NaCl–0.4LiF additives, have been prepared by solid-state synthesis. The effect of additives on the phase formation, structural parameters, and dielectric and ferroelectric properties of the ceramics has been studied. A decrease in the ceramic sintering temperature is found. A slight increase in the unit-cell volume upon modification of the ceramics under study by lithium fluoride and 0.6NaCl–0.4LiF additive is revealed. First-order ferroelectric phase transitions near 700–800 K have been observed. The prospects for improving the piezoelectric properties of modified ceramic samples are proved.
