A kind of non-primary explosive percussion primers were made with the non-primary explosive charge composed of 50% （mass fraction）of 50 nm-sized Ti and 50%（mass fraction） of 5 μm-sized KClO₄. The output characteristics of the non-primary explosive percussion primer were studied by means of simulation experiment and high-speed photography. The experimental results show that when a firing pin with diameter of 1.0 mm hits the primer, the reaction form of drug in the primer is slow combustion. When a firing pin with diameter of 1.7 mm hits the primer, the reaction form of drug in the primer is deflagration. When a firing pin with diameter of 3.0 mm hits the primer, the reaction form of drug in the primer is explosion. When reacting in the form of slow combustion, the output flame intensity of the primer is very weak, the hot ash is 0, and the 50% characteristic ignition distance is 0. When reacting in the form of deflagration, the flame duration of the primer output is about 250 μs, the hot ash is 12.9 mg, and the 50% characteristic ignition distance is 94 mm. When reacting in the form of explosion, the flame duration of the primer output is about 50 μs, the hot ash is 7.7 mg, and the 50% characteristic ignition distance is 52 mm, whereas for the primary explosive charge composed of lead azide, 50 nm Ti and 5 μm KClO₄ in the same formula series, there is only one type of reaction form-explosion, the flame duration of the primer output is about 50 μs, the hot ash is 6.5 mg, and the 50% characteristic ignition distance is 32 mm. When the percussion primers without primary explosive is ignited in the form of deflagration, its ignition performance is better than that of the percussion primers with primary explosive in the same formula series.
