Superfine PETN thin layer slurry explosive

摘要

A cap-sensitive slurry explosive capable of propagating a high order detonation in thin layers and which has a high degree of safety for a cap- sensitive explosive. The slurry consists of a super-fine grained explosive, suspended in an energetic, but non-self-explosive liquid matrix and contains no liquid explosive ingredient. The slurry resists dispersion in a variety of liquids including water and crude oil. In the preferred embodiments the slurries include penetaerythritol tetranitrate (PETN) in super fine particles, having an average particle size of about 6.5 microns.
