Abstract

The compatibility, stability and the pyrolysis behavior of aluminum based solid-liquid compound fuel were systematically investigated by thermogravimetric analysis (TGA). The compound fuel lost its 30% weight before the temperature rose to 150 . AP decomposed at 210 and lead to 50% weight loss. The reaction between aluminum and oxygen was accelerated at 660 since the melting of solid combustible agent. The total weight loss after 1000 pyrolysis is about 80% for nitrogen atmosphere. On the contrary, the total weight loss for oxygen atmosphere is approximate 70% because of the generation of aluminum oxide. The microscopic structures and the elementary composition of the pyrolysis products were analyzed using scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS). The structures of the products after 200 pyrolysis are spherical and flaky. All these structures are destroyed after 1000 pyrolysis. Instead, massive structures were found in the products. Aluminum is the main element in the final pyrolysis products for all conditions. The second-most element in the product for nitrogen atmosphere is carbon. Carbon deposited accompany with the decomposition of paraffin or other organic components. The second-most element in the product for oxygen atmosphere is oxygen. This conclusion is attributed to the formation of aluminum oxide.
