Abstract
The thermal decomposition processes of magnesium, sodium nitrate, viton A and their mixing components were studied by differential thermal analysis (DTA) and thermogravimetry (TG) in order to obtain the condensed phase reaction mechanism of magnesium/sodium nitrate system. DTA and TG results showed that magnesium had a large mass loss after melting, the decomposition of sodium nitrate included different stages, and viton A decomposed completely in the narrow range of temperature. The thermal analysis for the mixtures indicated that the decomposition products of the viton A might react with magnesium, and with the decomposition products of sodium nitrate. The results suggest that fast decomposition of Mg/NaNO3happened at 535°C, while it happened at about 380'C after adding viton A to the system.
