Application

 

Potassium perchlorate is used in ammunition percussion caps, explosive primers, fireworks and propellants. It acts as a solid rocket propellant. It is also used as an oxidizer in colored pyrotechnic compositions and flash powder. It is used as an antithyroid and involved in the treatment of hyperthyroidism. The mixture of anthracene and sulfur with potassium perchlorate is used for generating black smoke signaling.
