A study of the process of thermal oxidation of lead selenide by the NMR and XRD methods

详细

Studies of the process of oxidation of powder samples of lead selenide in a dry air atmosphere have been performed. As shown by the methods of X-ray diffraction and scanning electron microscopy, the process of thermal treatment of samples resulted in the formation of the PbSeO₃ phase, aside from the initial PbSe phase. Studies by the method of nuclear magnetic response (NMR) allowed revealing the dynamics of changes in the spectrum under the changed thermal treatment conditions.
