  • Gelled-water bearing explosive composition
    Patent number: 4077820
    Abstract: A gelled water-bearing explosive comprising a water-soluble oxygen releasing salt such as ammonium nitrate, a fuel, water and a gelling agent. The gelling agent is an organic metallic complex of a metal with a copolymer of a water-soluble monomer and a monomer which forms, with a metal, a chelate ring.
