β¦ Synopsis
The isotlt~rmal hinetics an,2 self.heating in binary mix'~ures o~ magnesit, m and sodium nitrate l~ave been studied as a /unction of temperatme and reactant Β’ompo.dtion, The effects o t reduced press#res ( do~m to I0 -'t tor~) and o/replacing the air over the reactants by a~gon have been examined. Comparative studies o[ mi*t~es o/sodium nitrate witt~ magnesium oxide, aluminium oxide, and aIumlnium were also made. From these measurements it is concluded that mttgnesi,on is oxidized in the melt by oxFgen a~ems produced by th~ detompo~ition ol sodium nitrate and th#t it is the ~xothe~n~icity o/this reaction which leads to ignition.

## Abstract Temperature sensitivity of burning rate of magnesiumβsodium nitrate propellants has been determined at different mixture ratios in the temperature range between β 40Β°C and + 50Β°C. The results indicate that the temperature sensitivity is minimum at high magnesium loadings and increases a
