摘要：

The home-made heat exchanger method (HEM) apparatus has been adapted to the growth of NaMgF3 ingots. By unseeded crystal growth using presynthesized NaMgF3 the structure was maintained during growth. Twinning introduced by the high-temperature phase transition is observed in the crystal. Studies on the crystals, at high temperature, by optical microscopy, calorimetry and Raman scattering, show a unique phase transition, from orthorhombic (Pbnm) to cubic (Pm3m) structure, at about 770 degrees C.
