| Abstract: The thermal decomposition process of KAI(SO4)2·12H2O and its kinetics has been studied by TG-DTG.By Dollimore method, D3 is defined as the second step of thermal decomposition kinetic model and its kinetic equation is dα/dT = (1/β) CTm(3/2(1 - α)2/3[1-(1-a)1/3]-1).At the same time, it has been found that the apparent activation energy Eincreases with the increases of fraction of conversion a and the absolute temperature T, and then it shows that a linear relationship with the temperature Thas been obtained. |
