STUDIES OF: THE SYSTEMS OF RARE EARTH SESQUIOXIDESBERYLLIUM OXIDE EQUILIBRIUM AND METASTABLE EQUILIBRIUM RELATIONSHIP IN THE SYSTEM Gd_2O_3-BeO

In the La2O3-BeO binary system, two compounds, La2O3. 2BeO and 3La2O3.2BeO, have been identified, while others between rare earth sesquioxides and the beryllium oxide have not been hitherto reported. et al. by the high temperature thermal analysis method, ascertained the phase diagram of Gd2O3-BeO to be a simple eutectic binary system. No intermediate compound of any form has been found. However, according to their phase diagram,
