Thermochemische Untersuchungen zu den Systemen SE2O3-SeO2 IV. Lösungskalorimetrie der SE2SexO3+2x-Phasen (SE = Nd, Sm, Y) / Thermochemical Investigations on the Systems RE2O3-SeO2 IV. Solution Calorimetry of the Phases RE2SexO3+2x(RE =Nd, Sm, Y)

The solution enthalpies have been determined for the ternary phases RE2SexO3+2x existing on the pseudo-binary section RE2O3-SeO2 and for RE2O3 and SeO2 in 4n HCl (RE =Nd, Sm, Y). From these date the enthalpies of formation of the ternary phases have been derived via suitable solution schemes on the basis of the known enthalpies of formation of RE2O3 and SeO2.
