Copper Azide

Copper azide is a chemical compound with the molecular formula CuN3. It is an inorganic, explosive and highly reactive substance that is commonly used as a primary explosive or as a detonator in commercial explosives.

Copper azide is formed by adding sodium azide (NaN3) to a solution of copper sulfate (CuSO4). The reaction proceeds as follows:

2NaN3 + CuSO4 → Cu(N3)2 + Na2SO4

The resulting blue crystalline solid is extremely sensitive to heat, friction, and impact, making it a dangerous material to handle.

Copper azide decomposes violently when heated, releasing nitrogen gas and forming copper metal. The decomposition reaction is exothermic and rapid, leading to a sudden release of energy that can cause an explosion if the material is not properly handled.

Due to its unstable and hazardous nature, copper azide is rarely used in bulk quantities. Instead, it is typically synthesized and stored in small quantities for use in specialized applications such as primers for small arms ammunition, fuses, and detonators.
