Developing materials with high stability in such an atmosphere is crucial for meeting the actual needs of practical applications because the majority of functional materials lose their crystallographic sustainability at high temperatures and pressures under shock-loaded conditions. A series of shock pulses with Mach values 2.2 of 100, 200, and 300 have been applied to the PbS nanomaterials with an interval of 5 sec per shock pulse. To investigate the crystallographic, electronic, and magnetic phase stabilities, powder X-ray diffractometers (XRD), diffused reflectance spectroscopy (DRS), and vibrating-sample magnetometers (VSM) are used. The material exhibits a rock salt structure (NaCl-type structure), and the XRD indicates that it is monoclinic with the space group C121 (5). Further, the shift was observed as a result of the lattice’s contraction and expansion when the material was subjected to shock loading, which indicated the material’s stable structure in XRD.
