What is Lead Azide?
Lead azide is a special kind of chemical. It is made of two parts: lead and a group of atoms called an azide ion. The lead in this compound has a specific electrical charge, which chemists call a "+2 oxidation state".
Why is it an Explosive?
Most other chemicals that are similar to lead azide might just burn quickly. But lead azide is different. It explodes with a lot of force! Because of this, it is used as a "detonator." A detonator is like a tiny spark plug that sets off a much bigger explosion. It helps to start the main explosive material.
How is Lead Azide Made?
Scientists make lead azide by mixing two other chemicals together. They use lead(II) nitrate and sodium azide. When these two chemicals react, they create lead azide.
Safety and Handling
Lead azide is very dangerous and must be handled with extreme care.
- It can explode if it is dropped even a short distance, like 6 inches (15 cm).
- It can also react with other metals, such as copper. When it touches these metals, it can form even more sensitive and dangerous explosives.
- Unlike some other explosives, lead azide does not become less dangerous when it gets wet. It stays just as explosive.
- If someone needs to get rid of lead azide safely, it can be destroyed using a chemical called sodium dichromate.
