2005 Equilibria E 4000 Thermodynamic Assessment of the Mn—Y—O System. — A complete thermody- namic description of the title system is proposed and an optimized set of parameters of Gibbs energy functions for the compounds h-YMnO3 and YMn2O5 are given. YMn2O5 is stable from room temperature up to 1461 K. Then it decomposes into h-YMnO3 and β-Mn3O4. h-YMnO3 is stable above 1062 K and decomposes into YMn2O5 and α-Y2O3 at lower temperature. — (CHEN*, M.; HALLSTEDT, B.; GAUCKLER, L. J.; J.
