  • Method of manufacturing a cap-sensitive and non-sensitive aqueous gel suspension explosive
    Patent number: 3962001
    Abstract: Non-cap sensitive aqueous gel explosives containing no suspended solid fuels are made by combining water, hexamethylenetetramine, ammonium nitrate, sodium nitrate, ammonium perchlorate and nitric acid, along with sufficient polysaccharide gum to thicken the mixture. These explosives are rendered cap sensitive by mixing therewith paint grade aluminum powder or other conventional sensitizing agents. According to a preferred procedure, a cap sensitive aqueous gel explosive is made by a procedure in which nitric acid and aqueous hexamethylenetetramine solution are first combined under controlled conditions of temperature and pH and ammonium nitrate, sodium nitrate, ammonium perchlorate, thickening agent and aluminum powder are added in controlled amounts in a specified order. The products possess cap sensitivity, even at temperatures as low as minus 23.degree.C.
