Abstract

The thin films and powders of PbS, PbSe, and PbSe and PbS_0.5Se_0.5 have been obtained by chemical precipitation method. The X-ray spectra of the obtained thin layers were obtained through the"Miniflex 600" diffractometer, and elemental analyses were performed. Thermogravimetric analyses of the powders of all three compounds were conducted in the temperature range of 20-800°C using the "NETZSCH STA 449 F3" apparatus. It has been determined from the X-ray spectra that the angular positions of all the peaks of PbS, PbSe, and PbSe and PbS_0.5Se_0.5 thin layers coincide with the positions of the corresponding diffraction peaks obtained under normal conditions. The results of the thermogravimetric analysis measurements and calculations have shown that the compounds are consistent with the formulas of PbS, PbSe, and PbS0.5Se0.5 powders.
