【摘要】 以无水乙醇为非溶剂,采用机械研磨和低温干燥的方法制备了高氯酸.[四氨.双(5-硝基四唑)]合钴(Ⅲ)(BNCP)的超细粒子,测试了其粒度、比表面积、感度、热性能。结果表明,超细粒子粒度小于2μm;比表面积分布为3.88~13.9 m2.g-1;其撞击感度和摩擦感度均随比表面积的增大而逐渐降低;细化样的静电感度比原样大,但随比表面积增大而变化的趋势不明显;DSC热分解起始温度和峰温随比表面积的增大而有所提前。更多还原

【Abstract】 Tetraammine-cis-bis(5-nitro-2H-tetrazolato-N2) cobalt(Ⅲ) perchlorate(BNCP) superfine particles were obtained by fluid milling and cryogenic drying methods with absolute ethanol as non-solvent.Their particle sizes were mostly under 2 microns and their surface area were from 3.88 m2·g-1 to 13.9 m2·g-1.The results show that their impact sensitivity and friction sensitivity decrease with increase of surface area.Electrostatic sensitivity of superfine particles is higher than that of origin particles while they change indistinctively with increase of surface area.DSC exothermic onset temperature and exothermic peak temperature become lower with the increase of surface area.更多还原
