| 摘 要： | 亚铬酸铜是促进复合固体推进剂中高氯酸铵分解的一种很好的催化剂，但由于以往制备的亚铬酸铜及高氯酸铵超细微粒易发生团聚，不能有效地对高氯酸铵的分解起催化作用。本文使用高能球磨法，使纳米级亚铬酸铜嵌入或粘附于高氯酸铵晶体表面而形成复合粒子，因而大大地提高了对高氯酸铵的催化效果，使高氯酸铵的热分解反应温度区间明显前移，热分解反应的激烈程度大大提高

| Abstract: | Copper chromite was mainly used to catalyze and decompose ammonium perchlorate in solid composite propellant.Ulrafine particles of copper chromite and ammonium perchlorate easily aggregated each other,thus copper chromite can not catalyze ammonium.Perchlorate well enough in the compounds,we have preferably settled the problem.In this paper,we apply energetic ball milling method to embed nanometre copper chromite in the crystalloid surface of ammonium perchlorate to form compound particles.This method greatly enhances catalysis effect and results in more drastic thermolytic dissociation of ammonium perchlorate. |
