•Crystallographic phase stability of the poly-crystalline and single crystalline lithium sulfate monohydrate at shocked conditions is reported.•XRD and raman results show the stable crystal structure of poly-crystalline samples than that of the single crystalline samples at shocked conditions.•Poly-crystalline nickel sulfate hexahydrate sample has relatively high structural stability and shock resistance compared to the single crystal. In the present work, we demonstrate the interesting findings of shock wave recovery experiment conducted on poly-crystalline lithium sulfate monohydrate crystals (Li2SO4.H2O) under 50 and 100 shock pulses loaded conditions and the obtained results are compared to the obtained results of single crystal Li2SO4.H2O. The poly-crystalline Li2SO4.H2O samples neither undergo any crystallographic phase transitions nor shock wave assisted dehydration. But, the attained diffraction and Raman results indicate that, at shock loaded conditions, lots of structural deformation and distortions occur in the mother crystal structure by the impact of shock waves. Also, at shocked conditions, the super-paramagnetic state of Li2SO4.H2O is significantly affected and remarkable reduction (10–1 to 10–7) of the saturation magnetization is found.  Note that, in the case of single crystalline Li2SO4.H2O, the disordered crystal structure has been witnessed for shock loaded samples.
