ABSTRACT:

IR-spectroscopic, X-ray diffraction studies of the initial magnesium nitrate hexahydrate, intermediate and final products of its thermal decomposition in air were carried out. Thermographic analysis made it possible to determine the main parameters and the mechanism of thermolysis of a given salt. Friedman’s analysis shows the multistage process.

KEY WORDS:

thermal decomposition, thermolysis, magnesium nitrate hexahydrate, magnesium oxide, nitrous gases IR spectroscopy, X-ray diffraction, ASTM method, Friedman analysis.
