【摘要】 用DSC和TG,在不同的线性升温速率下,通过对比DSC和TG曲线及热特征温度,考察了分析纯硝酸铵(AN)、工业AN以及木粉与分析纯AN混合物的热分解行为,推断出了分解反应最概然机理函数和动力学方程。结果表明:AN中加入少量的木粉使热安定性显著降低。更多还原

【Abstract】 The kinetics of thermal decomposition reaction of analytical pure ammonium nitrate(AN),commercial pure AN and the mixture of analytical pure AN and wood powder are investigated by means of DSC and TG at various linear heating rates respectively.The most probable mechanism functions and kinetics equations of chemical reaction are presented.It is showed that the thermal stability of AN can be lowered by adding a small quantity of wood powder.更多还原
