Combustion phenomena of magnesium-sodium nitrate binary mixtures have been studied to find out burning rate variation at different oxidizer levels. The results indicated that the stoichiometric mixture of Mg-NaNO/sub 3/ was not the fastest burning, and mixtures containing a high proportion of magnesium burned faster. Differential thermal analyses indicated that the exothermic oxidation of magnesium in the condensed phase may be responsible for this variation in burning rate. The rise in heat energy in condensed phase at high fuel concentrations, followed by particle ejection and ignition in the flame zone, is seen as causing a high burning rate. It has also been found that the oxide coating of the metal particles increases with the oxidizer content, and metal agglomerates emitted from the surface may cause the reduction in burning rate. The photographs of the silver surface obtained after static tests support the suggested combustion behavior.
