| Abstract: | In this paper,the main application of TG-DTA technology in the thermal decomposition of hydrotalcite-like compounds was reviewed.The number of weight-loss stages and the peak on the TG-DTA figure and the temperature corresponded to the weight-loss procedure were represented.Based on relevant theories,the deduction methods of hydrotalcite-like compounds'chemical formulation,the calculation methods of kinetics parameters and the mechanics corresponded to thermal decomposition procedure were discussed in detail.Thus,the thermal decomposition behaviors were learned in an all-around way. |
