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
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. For best results, the aluminium powder should be "Dark Pyro" grade, with a flake particle shape, and a particle size of fewer than 10 micrometres.
Niche uses include lithium perchlorate, which decomposes exothermically to produce oxygen, useful in oxygen "candles" on spacecraft, submarines, and in other situations where a reliable backup oxygen supply is needed. [10] Potassium perchlorate has, in the past, been used therapeutically to help manage Graves' disease. It impedes production of ...

In the first part of the video, three eggs are placed in a glass and submerged in liquid nitrogen. After a few seconds they become rock hard and they are crushed to show how they shatter under the ...
Compatible with potassium chlorate. Less burning rate decrease than sodium carbonate. Incompatible with magnesium and aluminium, reacts evolving hydrogen gas. Yellow Sodium carbonate: Na 2 CO 3: Hygroscopic. Significantly decreases burning rate, decomposes evolving carbon dioxide. Strongly alkaline. Very effective colorant, can be used in small ...
