Title: Use of either regular or low-calcium heteropolysaccharide S-7 in explosives and compositions thereby produced

Abstract: Heteropolysaccharide S-7, either in the regular or low-calcium form, is used at levels from about 0.1 to 10%, preferably 0.1 to 3%, most preferably 0.2 to 2%, in aqueous ammonium nitrate solutions to provide explosive compositions which rapidly develop viscosity and can be easily adapted to field use.
