Abstract

A new oxide, Bi(Mg_1/2Ti_1/2)O₃ was prepared using a high-pressure high-temperature technique at 8 GPa and 1000°C. As-sintered Bi(Mg_1/2Ti_1/2)O₃ has the BiFeO ₃-type perovskite structure with the rhombohedral R3c. After ground, crystal structure changed to tetragonal P4mm. Structure parameters of tetragonal Bi(Mg_1/2Ti_1/2)O₃ were refined from laboratory X-ray powder diffraction data (a = 4.033(10) Å, and c = 3.938(10) Å). Bi(Mg_1/2Ti_1/2)O₃ does not decompress at ambient pressure, but the structure changed from rhombohedral to tetragonal on heating above 800° C. This phase transition was nonreversible. Bi(Mg _1/2Ti_1/2)O₃ is expected to be one of the end members of lead-free ferroelectric materials.
