Abstract
Magnesium hydride is a kind of attractive hydrogen storage material. In this article, the thermal decomposition characteristic of the pure nitrocellulose and the mixture of nitrocellulose with 5% MgH2 was investigated using an accelerating rate calorimeter. The kinetic parameters such as activation energy, Ea; preexponential factor, A; and self-accelerating decomposition temperature, TSADT, were also calculated. We easily showed that the decomposition reaction could be accelerated by adding MgH2, which indicated that MgH2 has an obvious catalytic influence on the decomposition of nitrocellulose. On the other hand, the calculated values of Ea and TSADT showed a decrease in thermal sensitivity with the addition of MgH2. These results were in accordance with our objectives. Therefore, MgH2 is very likely to be an important additive in propellants.
