A detonator comprising a shell with a secondary explosive base charge, igniting means and an intermediate pyrotechnical train, said train comprising a novel ignition composition with a specific redox-pair of a metal fuel and a metal oxide oxidant, said fuel being present in excess to the amount of stoichiometrically being required to reduce the metal oxide, the ignition composition being able to ignite said secondary explosive into a convective deflagrating state to reliably detonate the same. Use of said novel ignition composition for the ignition of secondary explosives in general.

[ What is claimed is:] [1.]1. A detonator comprising a shell with a base charge comprising secondary explosive at one end thereof, igniting means arranged at the opposite end thereof and an intermediate pyrotechnical train converting an ignition pulse from the igniting means to the base charge to detonate the same, the pyrotechnical train comprising an ignition charge comprising a metal fuel selected from Be, Mg, Ca, Sr, Ba, Ti, Hf, Al, Ga, In and Tl and an oxidant in the form of an oxide of a metal selected from periods 4 and 6 of the periodic table, the metal fuel being present in an excess relative to the amount stoichiometrically necessary to reduce the amount of metal oxide oxidant, said ignition charge generating a hot pressurized gas that is able to ignite said secondary explosive of the base charge into a convective deflagrating state to reliably detonate the same.
