    The balanced equation for the reaction is:- 3 KClO 4 + 8 Al → 3 KCl + 4 Al 2 O 3. The stoichiometric ratio is 34.2% aluminum and 65.8% perchlorate by mass. A ratio of seven parts potassium perchlorate to three parts dark pyro aluminium is the composition used by most pyrotechnicians.

  3. Potassium perchlorate - Wikipedia

    en.wikipedia.org/wiki/Potassium_perchlorate

    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).

    In contact with potassium nitrate (e.g. in black powder) produces potassium perchlorate and hygroscopic ammonium nitrate; no such reaction with sodium nitrate. Reacts with potassium chlorate, producing unstable, gradually decomposing ammonium chlorate; such combination has to be avoided. [1] Nitronium perchlorate

  5. Perchlorate - Wikipedia

    en.wikipedia.org/wiki/Perchlorate

    Perchlorate salts are typically manufactured through the process of electrolysis, which involves oxidizing aqueous solutions of corresponding chlorates.This technique is commonly employed in the production of sodium perchlorate, which finds widespread use as a key ingredient in rocket fuel. [5]

    Other rarely used oxidizers are ammonium and potassium perchlorate. Two main issues need to be addressed with respect to the oxidizer if one is using potassium nitrate. The most important issue is the purity of the material. If a purchased material does not perform satisfactorily it may be necessary to recrystallize the KNO 3. The second ...

  7. Potassium chlorate - Wikipedia

    en.wikipedia.org/wiki/Potassium_chlorate

    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.

    Another common igniter formula is BPN, BKNO3, or boron – potassium nitrate, a mixture of 25% boron and 75% potassium nitrate by weight. It is used e.g. by NASA . It is thermally stable, stable in vacuum, and its burn rate is independent of pressure.

  9. Screaming jelly babies - Wikipedia

    en.wikipedia.org/wiki/Screaming_jelly_babies

    The liquid potassium chlorate decomposes into potassium perchlorate and potassium chloride. 4 KClO 3 → KCl + 3 KClO 4. The potassium perchlorate decomposes into potassium chloride and oxygen. KClO 4 → KCl + 2 O 2. The sugar in the candy reacts with oxygen, forming water and carbon dioxide. The reaction is exothermic and produces heat, smoke ...
