亚铬酸铜/高氯酸铵超细复合粒子的制备与性能研究

采用搅拌研磨法制备了粒径小于０．１μｍ的亚铬酸铜超细粒子，然后在研磨腔内使高氯酸铵（ＡＰ）与亚铬酸铜超细粒子复合。复合粒子的形成，增加了亚铬酸铜与高氯酸铵的接触面积、提高了粒子的分散性及均匀性，使亚铬酸铜催化作用增强，ＡＰ的分解温度降低，进而使含ＡＰ复合推进剂的燃速提高。

Study of Ultrafine Particles of Copper Chromite-Ammonium Perchlorate Composite

The ultrafine particles of copper chromite were prepared by LG mixing grinder through chosing technical parameters. Under the special striking and pressing,ultrafine ammonium perchlorate (AP) copper chromite composite was made in the grinder cavity. With particles composited the interface of the two kinds of particles is increased,the dispersivity and homogenization of the particles are raised therefrom. The experimental results indicate that the catalyst effect of copper chromite is improved,and the decomposition temperature of AP is decreased. Employing the composite particles in composite propellant can increase its combustion rate.
