Structural Evolution of CL-20/DNB Cocrystals at High Temperature: Phase Transition and Kinetics of Thermal Decomposition

completely, leading to lattice collapse of cocrystal; simultaneously, CL-20 undergoes a transition process from beta phase to gamma phase. Ultimately, gamma-CL-20 gradually decomposes with increasing temperature. The activation energy of cocrystal is also obtained as 129 +/- 10 kJ/mol. The understanding of cocrystal explosive was deepened and the further application was promoted.
