光电子能谱和X射线能谱在推进剂催化燃烧研究中的应用

CATALYTIC COMBUSTION RESEARCH OF SOLID PROPELLANTS BY USING PHOTOELECTRON SPECTROSCOPY AND X RAY SPECTROSCOPY

应用光电子能谱和Ｘ射线能谱技术，测试固体推进剂燃烧前及中止燃烧后推进剂表面成分和化学状态变化，以研究添加少量铅、铜化合物和炭黑的催化燃烧过程。结果表明，铅盐能够提高燃烧速度，这是由于其分解产物ＰｂＯ／Ｐｂ具有催化作用，使得推进剂表面易于生成含碳物质。

By using photoelectron spectroscopy and X ray spectroscopy, the decomposition components on the flameout surface of solid propellants were determined and the combustion catalyzed by small quantity of lead or copper compound and carbon were investigated.The experimental results show that the combustion speed can be accelerated by lead salt because of the catalytic effect of the decomposed PbO/Pb which easily bring about formation of carbon on the combustion surface.But the addition of copper compound or carbon black just plays a role of assistant catalysis.
