Potassium Perchlorate is the inorganic salt with the chemical formula KClO4. It is a strong oxidizing agent. It is a colorless crystalline solid.
It is used in fireworks, ammunition for percussion caps, explosives primers. It is also used in propellants, flash composite and sparklers.
Process
Potassium perchlorate is prepared industrially by aqueous solution of sodium perchlorate with potassium chloride.
NaClO4 + KCl → KClO4 + NaCl
