Low-temperature synthesis under low oxygen pressure and thermodynamic properties of YbFe2O4-δ
The mixed-valence compound YbFe2O4-d was synthesized using a modified method that allows employing gaseous atmosphere with a controlled ratio of inert gas and oxygen. The stability range for YbFe2O4-d was determined at 1090 °C under reducing conditions. Thermodynamic characteristics for the formatio...

Thermodynamic characteristics for the formation of YbFe2O4-d from the simple oxides and from elements in the temperature range 700-910 °C have been calculated. The obtained results allow specifying the low-temperature part of Р-Т-Х diagram for the Yb-Fe-O system. |
