| Abstract: | The decomposition kinetics of basic zinc carbonate in nitrogen atmosphere was investigated in dependence on TG-DTA analysis under different heating rates.The non-isothermal kinetic parameters were acquired by means of Doyle-Ozawa and Kissinger method respectively,and the thermal decomposition mechanism of basic zinc carbonate was also analyzed with the Satava-Sestak method.The results showed that the reaction obeyed random nucleation and subsequent growth mechanism. |
