“…The Bi 1.6 Sc x Ti 2 O 7‐δ (BScTO) and Bi 1.6 In x Ti 2 O 7‐δ (BInTO) x = 0.2, 0.4, 0.6 pyrochlore compositions were obtained by conventional solid‐state reaction. A detailed description of the synthesis procedure can be found elsewhere 24,38–40 . The thorough Rietveld refinement of the X‐Ray difraction (XRD) pattern was performed by using FullProf software package to obtain structural characteristics 41 .…”

“…Also, the interaction between the doped BTO pyrochlores and metallic electrodes remains unclear. Previously, we experimentally obtained various doped BTO pyrochlores and analyzed the electrophysical properties at high temperatures (≥200°C) 24,36,37 . The electrical conductivity in doped BTO is stated to be strongly dependent on the nature and amount of the dopant atoms.…”

“…При дальнейшем повышении температуры дисперсия вновь увеличивается. В последних исследованиях методом изотопного обмена кислорода было установлено, что у сложных оксидов со структурой пирохлора анионы O 2− приобретают подвижность при T ≥ 250°С [27]. Это явление, по-видимому, наблюдается и у композита Важным этапом анализа данных, полученных методом импеданс-спектроскопии, является построение эквивалентной схемы (ЭС).…”

“…Compounds crystallizing in pyrochlore-type structures with a general formula of А 2 В 2 X 6 X' have attracted the attention of scientists for more than fi fty years [1][2][3][4][5][6]. The reason for this is elemental diversity.…”
