Abstract: (4 Views)

The performance and safety of the formulation of thermite compounds is highly dependent on the method of processing and preparation of the compounds. In this research, Al/CuO thermite was prepared by wet mixing and core-shell method. SEM/EDX/MAP, FTIR analyzes were used to characterize and control the quality of the thermite prepared, and thermal analysis was used to determine the thermal behavior. One of the main problems in using thermites is the high initiation temperature and the lack of proper initiation of these compounds. The results showed that the initiation temperature and thermal decomposition temperature in thermite prepared by the core-shell method is about 40°C lower than the decomposition temperature of thermite prepared by the wet mixing method. Also, the kinetic and thermodynamic parameters as well as the critical temperature of the explosion and the self-igniting decomposition temperature of thermites were investigated by Kissinger and Starink methods. The results of the calculations showed that the activation energy has increased from 1565 kJ/mol in the core-shell method to 1839 kJ/mol in the wet mixing method, which indicates that the thermite produced by the wet mixing method is harder to dissolve.
