| 摘 要： | 采用重结晶法制备了K0.333(NH4)0.667NO3复盐,运用扫描电镜(SEM)、X射线衍射(XRD)能谱和差热分析(DSC)等方法对复盐的微观形貌和晶体结构进行了表征。运用最小自由能原理,以燃烧温度、燃烧热、平衡态固相产物含量为目标函数,计算了K0.333(NH4)0.667NO3/C12H4O2体系燃烧热力学参数,设计出低烟雾输出点火药配方,对优化后配方的火焰感度、燃烧热效应进行了对比测试。结果表明:两种氧化剂达到了在分子间的均匀混合,晶型有序性高,热分解特征温度降低。与KNO3/C12H4O2点火药相比,K0.333(NH4)0.667NO3/C12H4O2点火药的火焰感度、燃烧热效应的降低值小于10%,而燃烧固相产物含量大幅度降低,烟雾信号特征减弱,对1.06μm激光的衰减率下降了73.9%。

| Abstract: | K0.333(NH4)0.667NO3 was prepared using a recrystalization method.The micro-morphology and crystal structure of K0.333(NH4)0.667NO3 were characterized by scanning electron microscopy(SEM),X-ray diffraction energy spectrum(XRD) and differential scanning calorimetry(DSC).Taking the equilibrium solid-phase products,combustion temperature and combustion heat as target functions,the combustion thermodynamic parameters of K0.333(NH4)0.667NO3/C12H4O2 were calculated using the least free-energy principle,and the low... |
