SOLID EXPLOSIVE COMPOSITION

摘要

"Solid Explosive Composition" This invention provides a solid explosive composition comprising a low-water content melt-in-fuel emulsion when prepared at elevated temperature which solidifies on cooling. The emulsion comprises a continuous phase containing water-immiscible fuel and emulsifier and a discontinuous phase containing oxidizer salt. A particulate material, preferably silica particles or a metal salt, effective as a nucleating agent is incorporated in the composition to reduce supercooling of the discontinuous phase and to accelerate crystallisation of the oxidiser salt. The presence of the nucleating agent enhances the proportion of discrete droplets which remain totally encapsulated in the solidified composition and enables solid products to be obtained from relatively low melting oxidiser salt melts.
