Provided is a bullet hit squib including: an electrical connection line; a glow wire connected to the electrical connection line; and a primary explosive charge by which an active substance is formed which can be ignited by the glow wire. The primary explosive charge is formed by a primary explosive which is free of heavy metals and contains silver azide. A method for producing a bullet hit squib is also provided.

A detonation transfer assembly is disclosed. A detonation transfer assembly may comprise an external casing comprising an input end and an output end axially opposite the input end, an explosive column spanning axially inside the external casing, a primary explosive disposed within the explosive column, and a secondary explosive disposed within the explosive column axially between the primary explosive and the output end. The primary explosive and/or the secondary explosive may comprise a thermally insensitive initiation material that resists at least one of detonation or thermal degradation in response to temperature increase rate of 3.3 C. per hour over at least twenty hours.

The invention is directed to a nitrogen gas generator comprising a housing having two ends, ignition means at one end of the housing and a gas outflow opening at the other end of the housing, a volume of a filter at the outflow opening, a volume of solid propellant comprising sodium azide, a binder, a coolant and between 1 and 10 wt % of iron (III) oxide. Between the ignition means and the volume of solid propellant an active layer is present. The active layer comprises between 60 and 90 wt % of sodium azide, between 1 and 15 wt % of a binder, between 0.1 and 10 wt % of a coolant and between 5 and 30 wt % of iron (III) oxide. The content of iron (III) oxide in the active layer is higher than the content of iron(III)oxide in the solid propellant.

Provided is a method for preparing copper azide and cuprous azide encapsulated by conductive metal-organic framework. The method uses a conductive copper-containing metal-organic framework material as a precursor, and completes the azidation of the precursor by means of a liquid-solid electrochemical azidation reaction. Copper azide and cuprous azide nanocrystals are highly uniformly embedded within a conductive framework, which may effectively avoid the agglomeration of copper azide and cuprous azide, and reduce static charge generated by friction, displacement, and the like. Meanwhile, the conductive framework may promote the effective transfer of charge, avoid the accumulation of static charge, and improve the electrostatic safety. In addition, the liquid-solid electrochemical azidation reaction has advantages such as being safe and efficient, having a short reaction time and having strong operability, and the preparation process is compatible with a MEMS process, which is beneficial for the application of copper azide and cuprous azide materials in micro devices.
