摘　　要：文献报道了Ho(NO_3)_3·5H_2O和Ho(NO_3)_3·(?)H_2O的热分解行为,但Ho(NO_3)_3·5H_2O脱水机理不清,Ho(NO_3)_3·4H_2O按文献[1]不能制出。六水、三水合物的热分解及与DMF的配位作用未见报道。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.
