Abstract: Thermodynamic data on Pr4+ - containing compounds are of interest because of their development as ionic conductors, superconductors, and alternative gate dielectrics.
Both PrO2 and Pr6O11 have fluorite-type Fm3m structure with a = 5.392 and 5.467, respectively, ( Pr4+O2 and Pr0.664+ Pr0.34 3+O1.83?0.17 ).
The goal of this work was to synthesize praseodymium dioxide and obtain its drop solution enthalpy to use for calculation of formation enthalpies of Pr4+ compounds from calorimetry.
