A study of the aggregative stability of the CeO2-ZrO2 system was carried out in various pH ranges of the medium. To create a mathematical model of the stability of aggregates, the generalized DLVO theory was taken. The parameters of the structural component of the potential energy of particle interaction are determined using the principle of minimum entropy production. The limiting particle sizes of an an aggregatively stable system are determined.

Проведено исследование агрегативной устойчивости системы CeO2-ZrO2 в различных диапазонах рН среды. Для создания математической модели устойчивости агрегатов была взята обобщенная теория ДЛФО. Определены параметры структурной составляющей потенциальной энергии взаимодействия частиц с помощью принципа минимума производства энтропии. Определены предельные размеры частиц агрегативно устойчивой системы.
