Formula:

KClO₄

Description:

Potassium perchlorate is a very common oxidiser in pyrotechnics. Composition based on perchlorates tend to be less sensitive than those based on chlorates, and perchlorates can be used with sulfur and sulfides. For these reasons potassium perchlorate is much preferred above chlorates. Drawback is its slightly higher price.

Sources:

Potassium perchlorate can be prepared at home. For this purpose, sodium perchlorate is prepared first by electrolysis. Then, by double displacement with potassium chloride, potassium perchlorate is prepared from this solution. The product is recrystallised, dried and powdered.

Hazards:

Potassium perchlorate is toxic, and breathing protection should be worn when handling fine powder, Potassium Perchlorate can be absorbed through the skin!!!!.

Oxidising

Harmful
