Abstract

A primer charge containing an oxidizing agent and an initiating explosive. The charge contains as the oxidant zinc peroxide and as the initiating explosive diazodinitrophenol and/or a strontium salt of mono- and/or dinitrodihydroxydiazobenzene. In correspondence with the content of the strontium salt employed, the charge can also be utilized with low tamping; alternatively, such tamping can be selected at will. The charge is furthermore distinguished by lead-free and barium-free combustion products so that the charge does not exhibit the properties which make the heretofore known primer charges deleterious to the health of humans.
