“…This is confirmed also by observation that formation of the monoclinic phase Lu 4 Al 2 O 9 takes place at 1650 1C and higher temperatures [6], but the samples treated below the melting point are commonly multiphase and contain in addition 3:5 and Lu 2 O 3 phases. This phase transforms at high temperature annealing into 3:5 and Lu 2 O 3 [11]. Lu 4 Al 2 O 9 , melts incongruently at 2000 1C, above which liquid and Lu 2 O 3 are in equilibrium [6].…”

“…On the other hand, studies of solidification of melts in Ref. [11] have shown that the perovskite phase can be nucleated only when sufficiently high supercooling is present at the solidification point. Thus, it can be concluded that the LuAlO 3 perovskite has a narrow stability range, approximately located at 1750-1930 1C, outside which it decomposes separating the two neighboring phases: Lu 4 Al 2 O 9 and Lu 3 Al 5 O 12 .…”
