Pyrotechnische AnzĆ¼ndmittel im Sinne der Erfindung sind Stoffe oder Stoffgemische, die eine pyrotechnische Wirkung entfalten kƶnnen.Pyrotechnic igniters in the context of the invention are substances or mixtures which can develop a pyrotechnic effect.

Insbesondere Gegenstand der vorliegenden Erfindung ist ein pyrotechnisches AnzĆ¼ndmittel, das in mechanischen, elektrischen oder opto-elektrischen AnzĆ¼ndsystemen eingesetzt werden kann.In particular, the subject of the present invention is a pyrotechnic igniting agent which can be used in mechanical, electrical or opto-electric ignition systems.

Aus dem Dokument DE 102010025104 A1 ist ein 5,5'-Azotetrazolat-Sprengstoff bekannt, der ein Eisen-, Kobalt-, Nickel-, Kupfer-, Cadmium- oder Guanylharnstoffsalz eines 5,5'-Azotetrazols oder ein Gemisch aus mindestens einem 5,5'-Azotetrazolat und mindestens einem Bistetrazolyltriazenat oder mindestens einem weiteren Metallsalz oder Guanylharnstoffsalz eines 5,5'-Azotetrazols umfasst. Die dort beschriebenen Salze sind neutral, d.h. weder sauer noch basisch. Zink- und Chromsalze des 5,5'-Azotetrazols sind gemƤƟ dem Dokument DE 102010025104 A1 nicht lagerbestƤndig. Weiterhin besteht das Problem, dass Tetrazen enthaltende pyrotechnische Gemische thermisch nicht hinreichend stabil sind, da sich Tetrazen bereits bei 120 Ā°C zersetzt.From the document DE 102010025104 A1 a 5,5'-azotetrazolate explosive is known which comprises an iron, cobalt, nickel, copper, cadmium or guanyl urea salt of a 5,5'-azotetrazole or a mixture of at least one 5,5'-azotetrazolate and at least one bistetrazolyl triazenate or at least one further metal salt or guanyl urea salt of a 5,5'-azotetrazole. The salts described therein are neutral, ie neither acidic nor basic. Zinc and chromium salts of 5,5'-azotetrazole are according to the document DE 102010025104 A1 not storable.
