MgH2对DNTF的热分解特性影响研究

为探究金属氢化物MgH2对DNTF的热分解特性的影响, 向DNTF中加入不同含量的MgH2进行差式扫描量热法(DSC)测试。为防止DNTF加热挥发采用完全密封坩埚。经过研究发现:MgH2能降低DNTF热分解反应的放热分解峰温,但不同含量的MgH2对DNTF的热分解影响不同,随着MgH2含量的增加,DNTF的放热分解峰温和分解活化能逐渐降低,MgH2的含量高于8%时,DNTF热安全性较大降低。

Relationship between the Standard Enthalpy of Formation and the Ratio of Standard Enthalpy of Formation and Exothermic Denitration Decomposition Peak Temperature of M(NTO)_n

A relationship is established, using the least squares method, between the standard enthalpy of formation and the standard enthalpy of formation divided by the exothermic denitration decomposition peak absolute temperature corresponding to β →0.
