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).
The white "special notice" area can contain several symbols. The following symbols are defined by the NFPA 704 standard. OX: Oxidizer, allows chemicals to burn without an air supply (e.g., potassium perchlorate, ammonium nitrate, hydrogen peroxide). W: Reacts with water in an unusual or dangerous manner (e.g., caesium, sodium, diborane ...
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.
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.

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.
