Установлено, что в данной системе в области составов х ≤ 0,2 образуются твердые растворы (ТР) с ромбоэдрической структурой. Определены структурные характеристики ТР данной системы. Показано, что параметры гексагональной элементарной ячейки aH и cH линейно возрастают с увеличением х. Приводятся результаты исследования диэлектрических свойств керамики полученных ТР. Установлено, что керамика проявляет свойства сегнетоэлектрика с размытым фазовым пере- ходом. При увеличении содержания BiCoO3 в системе (х &gt; 0,05) имеющий место для (NaBi)1/2TiO3 при Т &lt; 500 К переход в релаксорное состояние для ТР вырождается.</p></abstract><trans-abstract xml:lang="en"><p>The solid solutions with the rhombohedral distorted perovskite structure of the (1–x)(NaBi)1/2TiO3–xBiCoO3 system (x &lt; 0.2) have been prepared by solid state reactions. The unit cell parameters aH and cH for these perovscites were found to increase linearly with increasing x. The dielectric properties of the solid solutions undergo a diffuse ferroelectric phase transition at 590–610 K. For compositions with x &lt; 0.05, the transition to relaxor state at a temperature below 500 K was observed. At x &gt; 0.05 such a transition was not revealed.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cross L.-E. // Nature. 2004.
