Potassium perchlorate, chemical formula KClO₄, is a strong oxidizer. It is a colorless, crystalline substance that melts at about 610 °C. It is one of the most common oxidizers used in fireworks, used variously in propellants, flash compositions, stars, and sparklers. It has been used as a solid rocket propellant, though it has mostly been replaced by the higher performance ammonium perchlorate.

It has a molar mass of 138.55 g/mol.

Reactions

---

As an oxidizer, KClO₄ reacts with a wide variety of fuels. A common example is Glucose, C₆H₁₂O₆.

3 KClO₄ + C₆H₁₂O₆ → 6 H₂O + 6 CO₂ + 3 KCl

And when mixed with cane sugar, can be used as an explosive.
