The effect of crystal structure on the thermal reactivity of CL-20 and its C4 bonded explosives (I): thermodynamic properties and decomposition kinetics
Original language description
The crystal structure, thermal behavior, and decomposition kinetics of epsilon-CL-20, RS-epsilon-CL-20, alpha-CL-20, epsilon-CL-20/C4, and RS-epsilon-CL-20/C4 were investigated by nonisothermal FTIR, TG, and DSC techniques. It was found that the thermaldecomposition of alpha-CL-20, epsilon-CL-20/C4, and RS-epsilon-CL-20/C4 could be considered as a two-step process and the initial step is partly controlled by crystal structure. However, the crystal structure could only affect the initial step of decomposition and the total heat release, and the heat release of RS-epsilon-CL-20 is the highest compared with alpha- and normal epsilon-CL-20. In addition, the activation energy of studied materials was calculated by Kissinger method and modified KAS method,which was compared with the results obtained by other researchers. It was indicated that the obtained activation energy of epsilon-CL-20 by Kissinger method is about 176.0 kJ mol(-1), which is almost the same with the results from the lit
