BNCP超细粒子的制备和表征

Preparation and Characterization of BNCP Superfine Particles

采用机械研磨和低温干燥的方法获得了高氯酸·[四氨·双(5-硝基四唑)]合钴(Ⅲ)(BNCP)的超细粒子。细化后,BNCP粒子外形趋于圆滑,粒度分布在亚微米至2μm之间;比表面积由细化前的0.087m2·g-1增大至10.8m2·g-1,撞击感度和摩擦感度均有所降低。

Tetraammine-cis-bis（5-nitro-2H-tetrazolato-N2） cobalt （ Ⅲ ） perchlorate （BNCP） superfine particles were obtained with fluid milling and cryogenic drying methods. The results show that their morphology become round and smooth, their particle sizes distribute from submicron to 2 μm,their surface areas increase from 0.087 m^2·g^-1 to 10.8 m^2·g^-1 ,and their impact sensitivity and friction sensitivity decrease.
