在乙二醇体系中，采用 PVP（聚乙烯吡咯烷酮，K?30）分散沉淀法，制备了亚微米级的六硝基合钴酸钾 K3 Co （NO2）6，使用扫描电子显微镜（SEM）、X 射线衍射分析仪（XRD）和差示扫描量热仪（DSC），对产物的粒径、形貌、组成及对AP 热分解的影响等特性进行了表征和研究，并对 K3 Co（NO2）6机械感度进行了研究。结果表明，在一定范围内，随温度升高，产物粒径增大，粒子表面变得粗糙；随 PVP 含量增加，粒径也在变大，团聚现象严重；与水和丙三醇相比，用乙二醇作溶剂时得到的产物粒径小，分散性好；K3 Co（NO2）6感度测试结果为撞击感度 H50＞60 cm，摩擦感度是0％；3％750 nm 的 K3 Co （NO2）6使 AP 的高温分解温度降低124．4℃，DSC 表观分解热由574．7 J／ g 提高到1332．5 J／ g。

The K3 Co(NO2 ) 6 submicron particles were prepared by co?precipitation method which is dispered by PVP in the ethylene glycol.The diameter,morphology,components and its influence on the thermal decomposition of AP were researched by Scanning Electronic Microscopy,X?ray Diffractometry and Differential Scanning Calorimeter. The mechanical sensitivity of K3 Co (NO2 ) 6 was studied also.The results show that the product particle size increases and its surface becomes rough as temperature ri?ses.The particle dimension increases and the agglomeration of the particles become serious as PVP increases.Compared with glycerol and water,smaller size and good dispersity product can be obtained using ethylene glycol as solvent.The impact sensitivity of K3 Co (NO2 ) 6 is H50>60 cm,and the friction sensitivity is 0%;3% 750 nm K3 Co(NO2 ) 6 can decrease high?temperature thermal?decom?position peak temperatures of AP by 124.4 ℃ respectively,and increase the DSC heat release of AP from 574.7 J/ g to 1 332 J/ g.
