| 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. |
