| Abstract: | The study of thermolysis of three holmium nitrate hydrates was undertaken, revealing a series of decomposition stages and each end-product being the oxide, Ho2O3.A thermal decomposition mechanism of the compounds is proposed and the apparent active energy values of dehydration are calculated with Kissinger method. The coordination of the hydrates with DMF was also studied by elemental analysis, infrared spectra, thermoanalysis, and X-ray diffraction. |
