Abstract

The thermal decomposition of [Co(NH3)5CO3]NO3, [Co(NH3)5NO2](NO3)2 and [Co(NH3)5H2O](NO3)3 complexes was studied by simultaneous TG, DTG, DTA (Derivatograph-C), termogastitrimetry, continuous selective water detection, TG-MS, and XRD methods. Due to the nearly explosive reaction of these complexes the samples were heated in a labyrinth-type crucible after a 10-fold dilution with alumina. Through the quantitative determination of NH3 and H2O it was possible to reveal the subtleness of decomposition of these complexes. Based on the qualitative and quantitative results obtained by the different thermoanalytical techniques used the equations of decomposition are given for both stages of the reactions.
