| Abstract: | The thermal decomposition processes PCC was studied in Nitrogen using TG-DSC.The result shows the thermal decomposition processed of PCC in Nitrogen is a one step.The multivariate non-1inear regression method in dynamic analysis to thermal decomposition of PCC was used,then factors of kinetics were obtained such as the most probable mechanism function,the activation energy,the pre-exponential factor. |
