    • A method for the preparation of neat energetic powders, having nanometer dimensions, is described herein. For these neat powder, a solution of a chosen energetic material is prepared in an aprotic solvent and later combined with liquid hexane that is miscible with such solvent. The energetic material chosen is less soluble in the liquid hexane than in the aprotic solvent and the liquid hexane is cooled to a temperature that is below that of the solvent solution. In order to form a precipitate of said neat powders, the solvent solution is rapidly combined with the liquid hexane. When the resulting precipitate is collected, it may be dried and filtered to yield an energetic nanopowder material.
    • 本文描述了制备具有纳米尺寸的纯能粉末的方法。 对于这些纯净的粉末,在非质子溶剂中制备所选择的高能材料的溶液,然后与与这种溶剂混溶的液体己烷组合。 所选择的能量较低的液体己烷比在非质子传递溶剂中溶解,而液体己烷被冷却至低于溶剂溶液的温度。 为了形成所述纯粉末的沉淀物,溶剂溶液与液体己烷快速组合。 当收集所得沉淀物时,可将其干燥并过滤以产生能量高的纳米粉末材料。
