Dynamic Shock Wave-Induced Amorphous-to-Crystalline Switchable Phase Transition of Lithium Sulfate

In recent years, there have been significant efforts made by materials science researchers to search for new phase-change materials, especially those possessing the caliber of influencing switchable phase changes, i.e., crystal−crystal and crystal−amorphous changes. Phase-change materials of such kind have attracted tremendous demand for technologically important applications, such as current resistive memories and thermal energy storage. In the present article, the switchable amorphous−glassy−crystalline−amorphous phase transitions occurring in the samples of lithium sulfate have been systematically experimented and demonstrated at dynamic shock wave-loaded conditions of various counts of shock pulses. The shocked samples have been evaluated using powder X-ray diffraction (PXRD), ultraviolet−visible (UV−vis) spectroscopy, and Raman spectroscopy. The shock wave-induced orientational order−disorder of the SO4 tetrahedron and the positional disorders of the lithium atoms led to the observed switchable phase transitions with respect to the number of shock pulses.
