Use
Potassium perchlorate is a strong oxidizing agent. Explosively decomposes at or over 400°C. Decomposed by organic matter (reducible material) and on concussion [Merck 11th ed. 1989]. Mixture with powdered magnesium is a friction-sensitive explosive [Safety Eng. Reports 1947]. Incompatible with reducing agents, such as: metal powders aluminum, titanium, barium, magnesium, nickel, and various metal hydrides, sulfur.
