The Thermal Decomposition of NiC₂O₄·2H₂O: An In situ TP-XRD and TGA/FT-IR Study

The non-isothermal decomposition of NiC₂O₄·2H₂O was investigated under a dynamic inert atmosphere using a temperature-programmed X-ray diffractometer (TP-XRD) and a thermogravimetric analyzer coupled to a Fourier-transform infrared spectrometer (TGA-FTIR). Both solid and gaseous products were analyzed in situ. The XRD pattern of the dehydration product did not match data for NiC₂O₄ reported in the JCPDS file. The thermal decomposition of the dehydration product (NiC₂O₄) took place in two sub-steps, both of which involved CO₂ evolution. Metallic nickel was the final product.
