Description

Structure of langacite is refined by precision x-ray diffraction data and structure of Pb3Ga2Ge4O14 is determined. Possibility of existence of right and left modifications and bonded with it formation of doubles is considered. For the large number of the family representatives crystallochemical analysis of dielectric properties are done. Correlation between details of crystal structure of langacites and their piezoelectric characteristics are discussed

Abstract (Russian)

По прецизионным рентгенодиффракционным данным уточнена структура лангасита, а также определена структура Pb3Ga2Ge4O14. Рассмотрена возможность существования правых и левых модификаций и связанное с этим образование двойников. Для большого числа представителей семейства проведен кристаллохимический анализ диэлектрических свойств и обсуждены корреляции между деталями кристаллического строения лангаситов и их пьезоэлектрическими характеристиками
