A slurry explosive composition, containing no liquid self-explosive sensitizing ingredient, comprises an inorganic nitrate, chlorate, or perchlorate, a fuel, water, and a particulate waterinsoluble combustible cellular material to increase the sensitivity of the composition. The inorganic salt may be ammonium or sodium nitrate as powder or prills. Water-soluble fuels are urea, sucrose, molasses, alcohols, glycols, or glues; other fuels are sulphur, aluminium, silicon, magnesium, boron, ferrosilicon, dinitrotoluene, nitrobenzene, charcoal, anthracite, asphalt, sawdust, wheat flour, dextrins, and starches. Suitable cellular material is cork, coke, and organic polymeric foams of, for example, polystyrene, polyurethane, polyethylene, polypropylene, polyvinyl chloride, polybutadiene, and rubber. The composition may also include wax/woodmeal, ethylene glycol as a dispersing agent, guar gum as a thickening agent, zinc chromate as a cross-linking promoter, tartaric acid as a cross-linking retardant, and ethyl hexanol as an anti-foaming agent.</p> |
