Ammonium perchlorate consists of the ammonium cation (NH₄⁺) and the perchlorate anion (ClO₄⁻). It is highly reactive, especially when combined with fuels or reducing agents.
Primary Uses of Ammonium Perchlorate
1. Solid Rocket Propellant
Ammonium perchlorate is a key oxidizer in solid rocket motors, particularly in missile systems and space launch vehicles such as the NASA Space Shuttle boosters. It is typically combined with a fuel like powdered aluminum and a binder (HTPB) to form a composite propellant.
2. Military Applications
Ammonium perchlorate is used in pyrotechnics, explosives, and ammunition. It also plays a role in gas generators and decoy flares.
3. Fireworks and Pyrotechnics
Although alternatives are often preferred due to environmental concerns, ammonium perchlorate is sometimes used in fireworks and other pyrotechnic devices.
