Abstract:

Standard enthalpies of formation of GdBaCo2-xMxO5.5 (M = Fe, Mn; x=0, 0.2) from constituent oxides. Delta H-ox(i)o, and elements, Delta H-f(i)o, at 298 K were calculated using dissolution enthalpies of corresponding double perovskites. Both Delta H-ox(i)o and Delta H-f(i)o were found to decrease in the sequence of GdBaCo2O5.5, GdBaCo1.8Fe0.2O5.5 and GdBaCo1.8Mn0.2O5.5 indicating growth of relative thermodynamic stability of GdBaCo2O5.5 caused by the substitution of Fe or Mn for Co.
