Abstract

1,143,902. Explosive compositions. INTERMOUNTAIN RESEARCH & ENG. CO. Inc. 14 March, 1967, No. 11895/67. Heading C1D. A slurry or gel blasting composition comprises at least 40% by weight of ammonium nitrate and/or sodium nitrate, water, and at least a sensitizing amount of finely divided aluminium having a lyophobic surface and a surface area of at least 0À5 sq. meter/gram. The aluminium may be in the form of paint grade particles or flakes, so as to provide a large number of tiny bubbles which act as detonation centres. Coarser aluminum metal and particulate magnesium may also be present. Reaction between aluminium and water may be inhibited by the addition of ammonium or an alkali metal phosphate or phosphite. Guar gum, a flour, or cooked starch may be present as a thickening agent. To improve the oxygen balance, a fuel may be added, e.g. a liquid or solid hydrocarbon, glycol, alcohol, or ether, coal, gilsonite, starch, sugar, or molasses. When sodium nitrate is present, sulphur is also added; chlorates and perchlorates may also be present. In one example, aluminium powder coated with stearic acid is used. The water in the composition may be partially substituted by a glycol or alcohol. Granules of TNT or smokeless powder may be included.
