稀土金属燃烧剂的研究综述

A REVIEW OF RESEARCHES ON MISCHMETAL INCENDIARY AGENTS

稀土金属化学性质较活泼，易于发生氧化反应，有较低的发火点和较高的燃烧热值，适于制造自燃燃烧剂。稀土金属燃烧剂可分为复合型和合金型两类，能自燃（或易于引燃），应用于弹药，使之具有穿甲（半穿甲）、爆破、杀伤、燃烧复合功能。所对付的目标主要是机动装置的燃油系统，仓库目标，有生力量等。对稀土金属燃烧剂的研究国外（主要是美国）已告一段落，在我国还方兴未艾。我国有着丰富的稀土资源，利用稀土金属的特点，研究比现有燃烧剂性能优越、功能独特的燃烧剂是燃烧剂发展的一个方向。

Researches on mischmetal incendiary agents are reviewed.Because of its active chemical properties,low ignition point and high combustion heat,mischmetal is fit for use as pyrophoric incendiary agents.Mischmetal incendiary agents can be devided into two kinds: the composite type and the alloy type.Mischmetal incendiary agents are usually used to provide explosive,killing,or armor-piercing munitions with incendiary ability.The targets of such munitions are e.g.fuel tanks of military trucks or aircrafts,and other combustibles or personnels.Research and application of mischmetal incendiary agents are becoming mature.China is rich in mischmetal resources.The search for more effective mischmetal incendiary agents with special properties should be a direction in the development of incendiary agents.
