摘要： 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.

摘要： A method for producing fine-grained triamino-trinitrobenzene (TATB) powders having improved detonation-spreading performance and hence increased shock sensitivity when compared with that for ultrafine TATB is described. A single-step, sonochemical amination of trichloro-trinitrobenzene using ammonium hydroxide solution in a sealed vessel yields TATB having approximately 6 &mgr;m median particle diameter and increased shock sensitivity.

摘要： A heating device for applying heat to the interior of a closed container containing a liquid therein to be heated includes an elongate cartridge-type electric heating unit and at least one heat pipe having a heat absorbing end and a heat transmitting end. The electric heating unit is attached to the heat absorbing end of each heat pipes and the heating device is secured in an aperture in the wall of the container by means of a mounting flange. The electric heating unit is mounted in an aperture in the mounting flange and the heating unit and at least one heat pipe attached thereto extend into the interior of the chamber to apply heat to the liquid in the container.
