相稳定硝酸铵及其混合物的热分解

硝酸铵（AN）是低特征信号推进剂和无烟推进剂的首选氧化剂，但存在点火、燃烧困难等问题。降低硝酸铵的热分解温度，促进AN的热分解是解决硝酸铵推进剂点火和燃烧困难的途径之一。本实验采用DSC和TG-DTG技术研究了金属氧化物、金属盐、含能粘合剂和六硝基六氮杂异伍兹烷（HNIW）对AN热分解的影响。结果表明，催化剂在一定程度上都降低了AN的吸热分解温度；含能组分加速了AN的放热分解过程。

Thermal Decomposition of Phase Stabilized Ammonium Nitrate and Its Mixtures

Ammonium nitrate(AN), used as oxidizer of low signature and smokeless propellants, is a promising candidate. However there are some problems for AN-based propellant in ignition and combustion. One way to resolve ignition and combustion difficulties for AN-based propellant is to lower AN decomposition temperature, and to accelerate the thermal decomposition of AN. Effect of metal oxide, organic metal salt (OME), energetic binder and hexanitrohexaazaisowurtzitane(HNIW) on the thermal decomposition of AN are studied by DSC and TG-DTG. Results show that catalysts lower the endothermic decomposition temperature of AN to a certain extent and energetic components accelerate the exothermic decomposition process of AN.
