  • Emulsion phase having improved stability
    Patent number: 6808573
    Abstract: A method is disclosed for forming a stable, water-in-oil emulsion phase containing a polymeric emulsifier. The addition of an animal oil or fatty acid additive enhances the long-term stability of the emulsion phase following homogenization.
    Type: Grant
    Filed: September 23, 2002
    Date of Patent: October 26, 2004
    Assignee: Dyno Nobel Inc.

  • High energy explosive containing cast particles
    Patent number: 6702909
    Abstract: The present invention relates to a water-based explosive having detonation properties similar to dynamite. It comprises an emulsion explosive formed by blending an emulsion phase with cast particles. The emulsion phase comprises a continuous organic liquid fuel phase, a discontinuous inorganic oxidizer solution phase and an emulsifier. The cast particles comprise a mixture of sodium perchlorate, water and diethylene glycol. The cast particles can be added to the emulsion phase before the particles are completely cured and thus before they reach final sensitivty.
