用气流粉碎机对原料高氯酸铵（ AP ）进行粉碎，行星球磨机对粉碎后的AP 进行球磨，使其球形化。用扫描电镜、微米粒度测试仪、傅里叶红外光谱仪、分别对比了原料AP、粉碎后AP和超细球形AP的形貌、粒度分布和红外光谱。用标准容器法和差示扫描量热法（ DSC）测试了同粒度超细球形AP和非球形AP的松装堆积密度和热性能。测试了同粒度超细球形AP和非球形AP的撞击感度和摩擦感度、吸湿性和结块性。结果表明，用球磨法制备的超细球形AP球形率高，球形度好，表面光滑，缺陷少，热分解温度向低温区移动。球形化后的AP撞击感度和摩擦感度降低，吸湿性和结块性明显改善。

Ammonium Perchlorate(AP) was smashed by jet mill,and then superfine spherical AP particles was prepared by planetary ball mill. Their morphologies,particle and IR spectra were characterized with scan electron microscope( SEM) ,Micron la-ser particle size analyzer and Fourier transform infrared spectrometer. Bulk density and thermal mechanical properties of superfine spherical AP and non spherical AP with the same size were characterized by standard container and differential scanning calorimeter (DSC).The impact sensitivity and friction sensitivity,hygroscopicity and caking of superfine spherical AP and non spherical AP with the same size were studied. The results show that superfine spherical AP prepared by the milling method has a high rate of sphe-roidization,good sphericity,smooth surface,fewer defects and thermal decomposition peak moves to low temperature. In addition, the impact sensitivity and friction sensitivity of superfine spherical AP are lower than the non-spherical AP,and hygroscopicity and ca-king are effectively improved.
