    摘要:

    采用溶液急冷重结晶和溶剂非溶剂重结晶相结合的方法得到了2,2′,4,4′,6,6′-六硝基茋(HNS) 高纯纳米颗粒。经过纳米化后,HNS的颗粒形貌更为圆滑,粒度分布处于58.9~231.6 nm之间,纯度由90.1%提高到99.44%,比表面积为19.27 m2·g-1。撞击感度测试表明,纳米HNS的撞击感度较之原料HNS有所降低,冲击片感度提高。

    Abstract:

    High purity nano HNS was prepared by the combination of solution quench recrystallization and solvent-antisolvent recrystallization. Results show that crystal appearance of nano HNS is smoother with particle size from 58.9 nm to 231.6 nm, and its purity is increased from 90.1% to 99.44%, the BET specific surface area is determined to be 19.27 m2·g-1. Sensitivity tests for the raw HNS and nano HNS indicate that nano HNS is less sensitive to impact than raw HNS, but more sensitive to short impulse shock waves.
