Spectroscopic and diffraction studies of polycrystalline copper sulfate pentahydrate at shocked conditions

Abstract

As per the literature reports available so far, there are numerous experiments that have been conducted and demonstrated on the crystallographic phase stability of a variety of materials such as metals, inorganic and organic materials by the impact of the shock waves. In the present course of work, we have selected one of the simple metal complex hydrate materials of copper sulfate pentahydrate (CuSO4·5H2O) for shock wave recovery experiment so as to examine the phase stability and shock wave induced dehydration process since it has a high possibility of undergoing phase transition with the sequence of 5H2O/3H2O/H2O. The molecular and crystallographic phase details have been examined by Raman spectroscopy and powder X-ray diffractometry (PXRD). Surprisingly, as per the observed spectroscopic and diffraction studies, the title material has not undergone any phase transition.
