Description

The exact composition of the yttrium tungstate hydrate is established on the basis of the roentgenographic and thermal analysis data. The parameters of its lattice are determined. It is shown, that the structure of the tungsten oxides (WO2 or W18O49), wherein part of the tungsten positions is occupied by yttrium and H2O (in form of a molecule or ion) is in the cavities between the layers, constitutes the basis of the Y2W3O12·3H2O crystalline lattice

Abstract (Russian)

Используя данные рентгенографического и термического анализа, установили точный состав гидрата вольфрамата иттрия. Определены параметры его решетки. Показано, что основой кристаллической решетки Y2W3O12·3H2O является структура оксидов вольфрама (WO2 или W18O49), в которой часть позиций вольфрама занята иттрием, а Н2О (в виде молекулы или иона) находится в пустотах между слоями
