Aplicação da calorimetria exploratória diferencial no estudo da cinética de transição alfa -> delta HMX

TRANSITION IN HMX.Octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) or octogen is a white crystalline substance which occurs in four polymorphous forms.It is used in a wide variety of military and industrial formulations owing to its suitable properties.Researchers have demonstrated the usefulness of this energetic material in explosive components.In the present work we apply differential scanning calorimetry (DSC) to measure the α → δ solid-solid phase transition energy of HMX.The results obtained by Kissinger's and Ozawa's methods were 487 and 495 kJ/mol, respectively.
