Thermal stability of ammonium nitrate systems containing d-metal nitrate salts under limited mass transfer conditions

Abstract The influence of cobalt, copper, iron(III), manganese and zinc nitrate salts on phase transitions thermal stability ammonium (AN) has been studied discussed. Differential analysis/differential scanning calorimetry coupled with thermogravimetry mass spectrometry were used to evaluate the analyzed systems. Each salt was appropriately mixed create samples AN:salt ratios 4:1, 9:1 49:1. It concluded that addition every influenced AN. Most decreased AN by accelerating its exothermic decomposition process. Iron cobalt nitrates defined as most hazardous additives, resulting in a creation highly destabilized mixture. Copper also catalysts process, lowering initial temperature increasing rate observed Zinc hexahydrate only considered be relatively neutral such systems, especially small amounts. study allowed define selected metal under conditions are potentially unsafe for
