    • Sol-gel chemistry is used for the preparation of energetic materials (explosives, propellants and pyrotechnics) with improved homogeneity, and/or which can be cast to near-net shape, and/or made into precision molding powders. The sol-gel method is a synthetic chemical process where reactive monomers are mixed into a solution, polymerization occurs leading to a highly cross-linked three dimensional solid network resulting in a gel. The energetic materials can be incorporated during the formation of the solution or during the gel stage of the process. The composition, pore, and primary particle sizes, gel time, surface areas, and density may be tailored and controlled by the solution chemistry. The gel is then dried using supercritical extraction to produce a highly porous low density aerogel or by controlled slow evaporation to produce a xerogel. Applying stress during the extraction phase can result in high density materials. Thus, the sol-gel method can be used for precision detonator explosive manufacturing as well as producing precision explosives, propellants, and pyrotechnics, along with high power composite energetic materials.
    • 溶胶 - 凝胶化学物质用于制备具有改进的均匀性的高能材料(爆炸物,推进剂和烟火),和/或可以铸造成近净形状和/或制成精密成型粉末。 溶胶 - 凝胶法是将反应性单体混合到溶液中的合成化学方法,发生聚合,导致高度交联的三维固体网络,导致凝胶。 高能材料可以在溶液形成期间或在该过程的凝胶阶段期间被引入。 组合物,孔和一次粒径,凝胶时间,表面积和密度可以通过溶液化学定制和控制。 然后使用超临界萃取干燥凝胶以产生高度多孔的低密度气凝胶或通过受控的缓慢蒸发以产生干凝胶。 在提取阶段施加应力可导致高密度材料。 因此,溶胶 - 凝胶法可用于精密雷管炸药制造,以及生产精密炸药,推进剂和烟火以及大功率复合材料。
