Ekologická zážehová slož obsahující ve smesi diazodinitrofenol nebo dinitrobenzofuroxany jako traskavinu, tetrazen jako senzibilizátor a silicid vápenatý jako horlavinu používá jako donor kyslíku oxaláty vybrané ze skupiny oxalát vápenatý, oxalát mednatý nebo oxalát zinecnatý. Jako další horlaviny je ve složi použito granulované vysoce porézní nitrocelulózy nebo granulované smesi nitrocelulózy a nitroglycerinu. Slož je vhodná pro výrobu a laboraci zápalek do náboju. Slož je možno laborovat do zápalek suchou i mokrou technologií. In the present invention, there is disclosed an environment-friendly igniting composition containing in a mixture diazodinitrophenol, or dinitrobenzofuroxanes as a primary explosive, tetrazene as a sensitizer, and calcium silicide as inflammable material, oxalates being selected from the group consisting of calcium oxalate, copper oxalate or zinc oxalate as oxygen donors. Granulated extremely porous nitrocellulose or granulated mixture of nitrocellulose and nitroglycerin is used as another inflammable material in the invented igniting composition. The composition according to the present invention is useful for the manufacture of cartridge caps and introduction therein. The composition can be introduced into the cartridge caps using both dry and wet technology.
