Gibbs Free Energy of Formation ofLn2CuBaO5Compounds Determined by the EMF Method (Ln=Yb, Tm, Er, Ho, Dy, and Gd)

Employing electrochemical cells with calcium fluoride solid electrolyte forLn=Yb, Er, Tm, Ho, Dy, and the Gibbs free energy change of the reaction of formation of the solidLn2CuBaO5“green” phase for subsequent lanthanide elements was determined. Obtained results were used to derive Gibbs free energy...

Description
Summary:Employing electrochemical cells with calcium fluoride solid electrolyte forLn=Yb, Er, Tm, Ho, Dy, and the Gibbs free energy change of the reaction of formation of the solidLn2CuBaO5“green” phase for subsequent lanthanide elements was determined. Obtained results were used to derive Gibbs free energy change of reactions of formation of respectiveLn2CuBaO5phases from constituent oxides.
