Kaliumperchlorat, chemical formula KClO 4, is a white solid, the potassium salt of the perchloric acid.

Kaliumperchlorat is strong oxidizing and delivers with heating oxygen. Therefore it is fire-promoting andalso in pyrotechnics one uses.

Mixtures of Kaliumperchlorat with phosphorus, sulfur or metallic powders can catch fire at low temperatures. They könnnen possibly. with simple hammer blow violently to the explosion to be brought. Therefore is also with the keepingto make certain from chlorates and Perchloraten that no contamination is in the storage container as present as possible.

However Perchlorate are more stable opposite chlorates (due to the Oxidationstoffe of the chlorine of +VII) and have therefore the chlorates with the use in pyrotechnic mixturesreplaced.
