Abstract

In-situ identification of metastable phases formed from the undercooled LuFeO ₃ melt under controlled oxygen partial pressure Po ₂ was studied by x-ray diffraction measurements at a synchrotron radiation source. Real-time observation of the formation and growth of individual phases during the single recalescence of Lu ₃Fe ₂O ₇ and LuFe ₂O ₄ phases at Po ₂ of 1 × 10 ³⁺ Pa has been revealed by a high speed imaging system at 1 kHz. The obtained diffraction pattern of the metastable phase in the LuFeO ₃ system was consistent with that of the metastable and stable phases reported in the Lu-Fe-O system.
