Abstract Ammonium nitrate (AN) is considered to be a very hazardous and difficult to handle component of mineral fertilizers. Differential thermal analysis coupled with thermogravimetry and mass spectrometry was used to determine the possible inhibiting effect of selected magnesium compounds on thermal decomposition of AN. Each additive was mixed with AN to create samples with AN:magnesium compound mass ratios of 4:1, 9:1 and 49:1. Most of analyzed compounds enhanced thermal stability of ammonium nitrate, increasing the temperature of the beginning of exothermic decomposition and decreasing the amount of generated heat. Magnesium chloride hexahydrate was determined to accelerate the decomposition of AN while magnesium sulphate, sulphate heptahydrate, nitrate hexahydrate together with magnesite and dolomite minerals were defined as inhibiting agents.

选择镁化合物作为硝酸铵分解的可能抑制剂

摘要 硝酸铵 (AN) 被认为是一种非常危险且难以处理的矿物肥料成分。差热分析结合热重法和质谱法用于确定选定的镁化合物对 AN 热分解的可能抑制作用。将每种添加剂与 AN 混合，制成 AN: 镁化合物质量比为 4:1、9:1 和 49:1 的样品。大多数分析的化合物增强了硝酸铵的热稳定性，增加了放热分解开始的温度并减少了产生的热量。确定六水氯化镁可加速 AN 的分解，而硫酸镁、七水硫酸盐、
