Metastable States in Alumina-Rich La2O3:Al2O3 and Nd2O3:Al2O3

Alumina‐rich mixtures of La2O3 and Al2O3 have equilibrium phases that are perovskite (LaAlO3) and β‐alumina (LaAl11O18). Annealing initially glassy samples with compositions 3La2O3–5Al2O3 or 11La2O3–14Al2O3 between 860° and 1075°C creates a metastable state that is clearly detected by X‐ray diffract...
