Stability Analysis of YbFe2O4 under Low Partial Oxygen Pressure

Resumo

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.
