The C→A transformation of Pr2O3 has been examined. The transformation is sluggish and takes place at and above 750°C. C-Pr2O3 is oxidized at a lower temperature than the A-form and oxidation proceeds in two stages in both cases. A hydrate Pr 2O3 . H2O, formed by the interaction of C-Pr2O3 and water at relatively high temperature, is described and its behaviour compared with that of Pr(OH)3. The C-form undergoes hydration at 40°C while the A-form does not. All the observations have been explained in terms of the defect structure of C-Pr2O 3.
