Bulk amorphous ZnSb under normal and high pressures: phase transformations and relaxation phenomena

Processes occurring upon heating of the high-pressure δ-Zn 41Sb 59 phase at atmospheric pressure were studied on bulk samples using scanning calorimetry and dilatometry in the temperature interval 170–573 K which includes the temperatures of amorphization and subsequent crystallization. Irreversible...

Zusammenfassung:Processes occurring upon heating of the high-pressure δ-Zn 41Sb 59 phase at atmospheric pressure were studied on bulk samples using scanning calorimetry and dilatometry in the temperature interval 170–573 K which includes the temperatures of amorphization and subsequent crystallization. Irreversible relaxation of the amorphous state followed by a heat release and elongation of the sample of the order of 1 4 of those found upon amorphization were observed at 325–425 K. At room temperature the effect of pressure on the electrical resistance of the amorphous Zn 41Sb 59 samples ( P
