Stability Analysis of YbFe2O4 under Low Partial Oxygen Pressure

Abstract

YbFe2O4 has been synthesized for the first time at 1090°C under reduced oxygen pressure. A distinctive feature of the synthesis is the use of a gas mixture consisting of an inert gas and a controlled amount of oxygen. Static method in combination with X-ray diffraction methods have been used to determine the thermal stability ranges for YbFe2O4. On the basis of the P–T–X data obtained, the Yb–Fe–O system diagram has been supplemented with low-temperature fragments, which is important for selecting the conditions for synthesis and operation of the compound.
