Description

In lithium niobate and lithium tantalate single crystals as well as in ceramic solid solutions of LixNa1-xTayNb1-yO3 ( x = 0 - 0.16; y = 0 - 1) the formation of structural element ordering is investigated. The processing procedure is determined for synthesis of charge materials, the methods of crystal growth and crystal doping are specified as well as the methods of measuring properties in niobate-tantalate base materials. It is shown that the use of structural ordering effects in the synthesis of complex ferroelectric systems with perovskite and pseudoilmenite structures on the basis of alkali metal niobates-tantalates permits designing materials with optimal combination of optical, electrical and thermal properties

Abstract (Russian)

Проведено исследование формирования упорядочения структурных единиц в монокристаллах ниобата и танталата лития и в керамических твердых растворах составов LixNa1-xTayNb1-yO3 ( x = 0 - 0.16; y = 0 - 1). Определены технологические режимы синтеза шихты, способы легирования, методы выращивания монокристаллов, методы контроля свойств материалов на основе ниобатов-танталатов. Показано, что использование эффектов структурного упорядочения при синтезе сложных сегнетоэлектрических систем со структурами перовскита и псевдоильменита на основе ниобатов-танталатов щелочных металов позволяет создавать материалы с оптимальным сочетанием оптических, электрических и тепловых характеристик
