Abstract
Results of polarising-microscope study of Na0.5Bi0.5TiO3 (NBT) crystals obt ained by the Czochralski method are reported. The nature of the observed do main structure is ferroelastic and the position of domain walls is stable i n the range 20-540 degreesC. The temperature dependence of extinguishing an gle psi between adjacent orientational states in the range similar to 200-3 50 degreesC is observed. Possibility of appearance of strong internal mecha nical stresses in NBT crystals at tetragonal-rhombohedral phase transition due to the different arrangement of Na1+ and Bi3+ ions in the A-position in these phases is discussed.
