Thermal Decomposition Kinetics of Ammonium Aluminum Carbonate Hydroxide

摘要：

　　The thermal decomposition of ammonium aluminum carbonate hydroxide was studied under non-isothermal conditions in air.The decomposition kinetics were evaluated from data of TG-DTA by means of the Kissinger equation and the Coats-Redfern equation.The values of the activation energy E,the preexponential factor A and the algebraic expression of integral G(α) functions of the thermal decomposition were calculated.The ammonium aluminum carbonate hydroxide (AACH) was characterized by X-ray diffraction,differential thermal analysis and thermogravimetric and field emission scanning electron microscopy.
