摘要：
The dehydration and decomposition behaviour of nickel chloride hydrate has been studied by a non-isothermal method with different experimental conditions such as heating rate, sample size, inert gas flow, etc. Kinetic parameters for the different steps of the dehydration and decomposition have been determined from DTA and TG curves using both model-independent and model-dependent methods of data analysis. The results are critically examined to determine meaningful kinetic parameters which, however, sometimes differ from those derived isothermally.
