Ammonium perchlorate
In the aerospace industry, ammonium perchlorate is the primary component of solid rocket propellants. It supplies the essential oxygen needed for fuel combustion—typically hydrocarbon-based materials—and releases vast amounts of energy to propel rockets. It is also used in certain pyrotechnic formulations to create unique visual effects. However, due to its explosive nature, stringent safety precautions must be implemented during production, storage, and handling.

Physical properties
It is a white crystalline solid with a density of approximately 1.95 grams per cubic centimeter. It is soluble in water—specifically, a certain amount of ammonium perchlorate can dissolve in water at room temperature—which makes it particularly valuable for applications in water-based systems.
Chemical properties
Perchlorate is a strong oxidizing agent. When heated, it undergoes a complex decomposition reaction, which can be represented as: 2NH₄ClO₄ → N₂↑ + Cl₂↑ + 2O₂↑ + 4H₂O↑. This reaction is highly exothermic and can react violently with reducing agents. As an oxidizer, perchlorate may trigger explosions upon contact with flammable or reducible materials.
