Total Claims: 7
Claim 1
Independent Claim
187 words
A cap-sensitive powdered explosive composition having no explosive components and having ammonium nitrate as its single oxygen releasing component, characterized in that said explosive composition, in addition to ammonium nitrate and further optional components useful in explosive compositions, contains all of the following four components in amounts within the respective ranges, in percent by weight of the explosive composition: (a) 3 to 8% of a combustible liquid consisting of one or more completely water soluble components, having a boiling temperature of above 120° C., and being capable of dissolving ammonium nitrate in amounts of between 20 grams and 100 grams per 100 grams of said liquid without reacting chemically with ammonium nitrate; (b) 0.5 to 2.5% of a water blocking agent consisting of a high molecular weight polysaccharide having the property of imparting high viscosity to an aqueous, saturated ammonium nitrate solution; (c) 0.5 to 3% of a water-insoluble wax or waxy substance in finely pulverized form; (d) 1 to 6% of an aluminium powder the particles of which are in flake form and which have a specific surface of at least 5000 cm 2 per gram.
