Herein, the crystallographic phase stability of the polycrystalline sample of sodium sulfate (Na2SO4) crystal at dynamic shocked conditions is reported and the phase stability profile of this sample with respect to the number of shock pulses is drawn from the outcomes of the X‐ray diffraction and Raman spectroscopic results. Interestingly, the polycrystalline sample does not undergo any high‐temperature polymorphic phases even at 100 shocked conditions. Note that the single‐crystalline Na2SO4 sample does undergo the crystallographic phase transition at dynamic shocked conditions. Based on the overall observed data, the polycrystalline sample has high shock resistance compared to that of the single‐crystalline sample and the obtained results are discussed elaborately. In addition to that, the present work can provide a shadow of light on the flow stress occurring on materials due to the influence of shock waves with respect to their existing state.
