The invention concerns lead- and barium-free igniter compounds with initial explosive substances mixed with oxygen-producing substances. The igniter compounds are characterized in that the initial explosive substances are selected from alkali metal salts and/or alkaline earth metal salts of dinitrobenzofuroxanes and the oxygen-producing substances are selected from metallic peroxides, nitrates of ammonium, guanidine, aminoguanidine, triaminoguanidine, dicyandiamidine and the elements sodium, potassium, magnesium, calcium, cerium and/or polyvalent metallic oxides. The igniter compounds according to the invention display higher stability with respect to known pollutant-free igniter compounds.
L'invention concerne des composés inflammateurs exempts de plomb et de baryum, comportant des substances explosives d'amorçage en mélange avec des substances produisant de l'oxygène. Ces composés inflammateurs se caractérisent en ce que les substances explosives d'amorçage sont sélectionnées parmi des sels de métaux alcalins et/ou des sels de métaux alcalino-terreux de dinitrobenzofuroxanes et les substances produisant de l'oxygène sont sélectionnées parmi des peroxydes de métal, des nitrates d'ammonium, de la guanidine, de l'aminoguanidine, de la triaminoguanidine, de la dicyandiamidine, ainsi que des éléments sodium, potassium, magnésium, calcium, cérium et/ou des oxydes métalliques polyvalents. Comparativement à des composés inflammateurs sans polluant, connus, ces composés présentent une meilleure stabilité.
