文摘

The combination of distillation, Bridgman–Stockbarger, hydrothermal recrystallisation and travelling molten zone (TMZ) methods were used for TlBr purification. Grown crystals were characterised by XRD rocking curve and FTIR spectroscopy methods, and by electrical measurements made from 200 to 300 K.
