Phase Equilibria in the Eu–Mn–O System

Phase equilibria in the Eu–Mn–O system were studied by X-ray powder diffraction in samples mechanically preactivated and prepared under an oxygen pressure of 10 –5 –10 2 kPa and in those prepared under a reductive atmosphere at a partial hydrogen pressure of about 5 kPa. –T and x–y projections of th...

Description
Summary:Phase equilibria in the Eu–Mn–O system were studied by X-ray powder diffraction in samples mechanically preactivated and prepared under an oxygen pressure of 10 –5 –10 2 kPa and in those prepared under a reductive atmosphere at a partial hydrogen pressure of about 5 kPa. –T and x–y projections of the P–T–x–y diagram of the Eu–Mn–O system and selected x – y isotherms of the Eu 2 O 3 –MnO–MnO 2 quasiternary system were plotted.
