The purpose of this study is to obtain high-entropy oxides with the magnetoplumbite structure, in which the Pb cation is used as a divalent metal cation. The synthesis conditions were optimized, and a technique was developed to avoid the evaporation of lead oxide. For the first time, single-phase samples of high-entropy oxides with the magnetoplumbite structure were obtained, its chemical composition is reflected by the formula PbFe2.4X2.4Y2.4Ga2.4In2.4O19. The particle size of the high-entropy phase is about 100 nm, which makes it promising for a number of applications. The effect of preliminary grinding of the initial components on the results of synthesis was studied. A synthesis mechanism is proposed. The results pave the way to synthesis and study of the properties of a new large subgroup of high-entropy oxides with the magnetoplumbite structure, which expands the possibilities of controlling the properties of ceramic magnetic materials.

Цель данного исследования – получение образцов высокоэнтропийных оксидов со структурой магнетоплюмбита, в которых в качестве катиона двухвалентного металла используется катион Pb. Разработана методика, позволяющая избежать существенного испарения оксида свинца в процессе синтеза. Впервые получены практически однофазные образцы высокоэнтропийных оксидов со структурой магнетоплюмбита, состав которых отражает формула PbFe2.4X2.4Y2.4Ga2.4In2.4O19. Размер частиц в некоторых случаях составляет порядка 100 нм, что делает их перспективными для ряда приложений. Изучено влияние предварительного перемалывания исходных компонентов на результаты синтеза. Предложен механизм синтеза. Полученные результаты открывают путь к синтезу и исследованию свойств новой большой подгруппы высокоэнтропийных оксидов со структурой магнетоплюмбита, что расширяет возможности управления свойствами керамических магнитных материалов.
