Аннотация
Для изучения процесса кристаллизации смешанного MnOx-ZrO2 оксида в различных средах применялись методы in situ рентгеновской дифракции и термогравиметрического анализа. В качестве референсного образца использовался чистый ZrO2. Показано, что процесс кристаллизации в Mn-содержащем образце зависит от среды: температура кристаллизации в восстановительной и инертной среде составляла 450–455 C, а в окислительной – 560 °C. Таким образом, добавление марганца привело к смещению температуры кристаллизации в сторону более высоких значений по сравнению с чистым ZrO2 (425 °C). Полученная кристаллическая фаза представляет собой твердый раствор Zr1-yMnyO2, а не чистый ZrO2. Вероятно, катионы Mn позволили стабилизировать тетрагональный диоксид циркония вместо моноклинного.
