Description

Mechanism and kinetics of transformation at the Y2O3/Bi2O3 boundary are studied through the method of physicochemical modeling of separate stages of interaction. The study was carried out through roentgenophase and microscopic analyses. It is established that interaction between Bi2O3 and Y2O3 proceeds through a number of parallel stages and is accomplished in the kinetic mode on the account of primary transfer of the Bi oxide components

Abstract (Russian)

Методом физико-химического моделирования отдельных этапов взаимодействия изучены механизм и кинетика превращений на границе Y2O3/Bi2O3. Исследование выполняли с помощью рентгенофазового и микроскопического анализов. Установлено, что взаимодействие между Bi2O3 и Y2O3 протекает через ряд параллельных стадий и осуществляется в кинетическом режиме за счет преимущественно переноса компонентов оксида Bi
