Thermoanalysis of ammonium perchlorate and sodium nitrate mixture

, 1983
A binary mixture of ammonium perchlorate-sodium nitrate in molar proportion undergoes partial fusion at 223°C and the transformation of the mixture to sodium perchlorate-ammonium nitrate occurs in the broad endothermic region.
