Potassium perchlorate in crystal form. Potassium perchlorate is prepared industrially by treating an aqueous solution of sodium perchlorate with potassium chloride.This single precipitation reaction exploits the low solubility of KClO 4, which is about 1/100 as much as the solubility of NaClO 4 (209.6 g/100 mL at 25 °C).
Hodgdon also makes "Triple Seven", a sulfur-free black powder substitute containing potassium perchlorate and 3-Nitrobenzoic acid, and "Black Mag3". [10] These are both more energetic by mass than black powder and can produce higher velocities and pressures.
With further heating, potassium perchlorate decomposes to potassium chloride and oxygen: KClO 4 → KCl + 2 O 2. The safe performance of this reaction requires very pure reagents and careful temperature control. Molten potassium chlorate is an extremely powerful oxidizer and spontaneously reacts with many common materials such as sugar.

This is a list of Superfund sites in Michigan designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law.The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

Perchlorate concentration was the highest in Chilean nitrate, ranging from 3.3 to 3.98%. [51] Perchlorate in the solid fertilizer ranged from 0.7 to 2.0 mg g −1, variation of less than a factor of 3 and it is estimated that sodium nitrate fertilizers derived from Chilean caliche contain approximately 0.5–2 mg g −1 of perchlorate anion.
