Formation of Co nanoparticles in the process of thermal decomposition of the cobalt complex with hexamethylenetetramine (NO3)2Co(H2O)6(HMTA)2 • 4(H2O)

The thermal decomposition of the cobalt complex with hexamethylenetetramine (NO3)(2)Co(H2O)(6)(HMTA)(2) center dot 4(H2O) was studied by the methods of differential thermal analysis, thermogravimetry, mass spectrometry, X-ray diffraction analysis, and by the magnetic method. It was established that the thermal decomposition of the complex in a current of an inert gas is accompanied by a pronounced exothermic process and formation of Co nanoparticles. It was shown that the kinetics of this process and the chemical nature of the decomposition products depend on the initial density of the sample under study.
