Barnhard, P IV; Kieres, F J

Hydrous metal oxides are described as thickeners for aqueous slurry explosives. The slurry explosives are of the type consisting of an inorganic oxidizing salt, an organic or inorganic fuel, water, and a thickening agent. The oxidizing salt, which preferably is ammonium nitrate or ammonium nitrite in admixture with sodium nitrate, is mixed with sufficient water to provide a fluid slurry. The water-oxidizing salt slurry, before or after the addition of the remaining slurry ingredients, is thickened with a colloidal hydrous metal oxide. The colloidal hydrous metal oxide may be finely divided alumina, silica gel or the like or may be a natural clay such as bentonite, attapulgite or kaolin. Any such inorganic material which thickens aqueous solutions may be utilized in the explosive slurries. Colloidal alpha alumina monohydrate is the preferred inorganic thickening agent. (26 claims)
