金属氢化物在含能材料中的燃烧、热分解及应用研究进展

为了促进金属氢化物材料在含能材料中的研究应用,从金属氢化物在含能材料中的燃烧、热分解和应用3个方面对金属氢化物在含能材料(EMs)中的研究现状和前景进行了概述。结果表明,在含能材料中加入适量的金属氢化物可以有效地改善混合体系的燃烧热、能量水平等其他方面的性能指标。将金属氢化物添加在含能材料中具有巨大的潜力,但金属氢化物与含能材料间的相容性及金属氢化物本身的稳定性等阻碍了金属氢化物在含能材料中的应用。其中,开发具有适当热稳定性的金属氢化物较为迫切。掺杂和纳米晶化是提高金属氢化物热力学性能最有效的两种方法。

Combustion,Thermal Decomposition and Application of Metal Hydride in Energetic Materials:an Extensive Literature Survey

The research status and prospect of using metal hydride as additives in energetic materials(EMs)are summarized in this study through three aspects:thermodynamics,energy and combustion performance of metal hydride in EMs.The results show that the combustion heat,energy level and some other performance indices of system are improved effectively,while opportune percentages of metal hydride are added in EMs.Despite huge potentials exist for the addition of metal hydride in EMs,some practical difficulties hinder the general application of them.Among them,the appropriate thermal stability of metal hydride should be developed and payed attention.Doping and nanocrystallization are two useful ways to improve the thermodynamics performance of metal hydride.
