| 摘 要： | 为研究水和硝酸铁(Fe(NO3)3)对硝酸铵(NH4NO3)的危险性,利用C80微量热仪模拟密闭环境,对浓度为100%、95%、90%的NH4NO3溶液,以及含有1%、2%、3%、4%四种不同Fe(NO3)3杂质含量的95%NH4NO3溶液进行热分析。结果表明:随着NH4NO3浓度的增加,NH4NO3溶液的活化能下降,热分解的难度降低。水抑制了NH4NO3的热分解,提高了其自反应起始温度(Tonset)。95%NH4NO3Tonset为238.89℃,加入Fe(NO3)3之后Tonset下降,Fe(NO3)3含量2%时Tonset为201.13℃,下降了37.76℃,Fe(NO3)3对95%NH4NO3溶液中NH4NO3热分解有"催化作用"。
