Abstract
662,346. Ammonium nitrate explosives. ATLAS POWDER CO. Feb. 7, 1949. [Feb. 26, 1948] No. 3303/49. Class 9 (ii). An explosive composition comprises crystallized granules of ammonium nitrate having from 4 to 11 per cent, based on the ammonium nitrate, of potassium nitrate distributed in solid solution throughout the structure of the ammonium nitrate, the granules being of a size such as to pass a U.S.S. No. 8 screen and be held to the extent of at least 70 per cent on a U.S.S. No. 70 screen, and the granules being sensitized with up to 20 per cent of an explosive liquid nitric ester, e.g. nitroglycerine, with or without nitrosugars or nitroglycols. The potassium nitrate may be added to the evaporating equipment before addition of the ammonium nitrate or to the molten ammonium nitrate in the graining kettle after evaporation ; grain modifying salts such as ammonium chloride and ammonium sulphate may be added. Alternatively the ammonium nitrate-potassium nitrate mixture may be prepared by nitric acid neutralization of a mixture of ammonia and potassium hydrooxide or carbonate. Other ingredients are sodium nitrate, cornflour, apricot pit pulp, wood pulp, bagasse, and chalk.
