Abstract
The subject of the present invention is lead- and barium-free propellant charges with primary explosives mixed with oxygen-supplying substances, characterized in that the primary explosives are selected from alkali metal and/or alkaline earth metal salts of dinitrobenzofuroxanes and the oxygen-supplying substances are chosen from metal peroxides, nitrates of ammonium, guanidine, aminoguanidine, triaminoguanidine, dicyanodiamidine, and the elements sodium, potassium, magnesium, calcium, cerium, and/or multivalent metal oxides.The propellant charges according to the invention exhibit increased stability with respect to known propellant charges that are free of harmful substances.
