亚铬酸铜是促进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超细微粒易发生团聚，因而并不能最有效地对高氯酸铵的分解起催化作用。本文采用溶剂－非溶剂法，使溶液变为过饱和而析出晶体，高氯酸铵晶体包覆纳米级亚铬酸铜形成复合粒子，较好地解决了这一问题。在复合粒子中，纳米级的亚铬酸铜微粒均匀分散于高氯酸铵中，由于亚铬酸铜纳米粒子具有很大的比表面积和很高的化学活性，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。
Copper chromite is a good catalyst for promoting the decomposition of ammonium perchlorate. However, the copper chromite and the perchloric acid ultrafine particles are prone to agglomerate in the past, The decomposition of the catalytic role. In this paper, the solvent-non-solvent method, the solution becomes supersaturated and precipitated crystals, ammonium perchlorate crystals coated with copper chromite to form nano-composite particles, a better solution to this problem. In the composite particles, nano-scale uniform distribution of copper chromite particles in ammonium perchlorate, copper chromite nanoparticles due to the large surface area and high chemical activity, thus greatly improving the high chlorine The catalytic effect of ammonium acid, ammonium perchlorate thermal decomposition reaction temperature range significantly forward, thermal decomposition reaction intensified greatly increased.
