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).
Any material which, in either concentration tested, exhibits a mean burning time less than or equal to the mean burning time of a 3:7 potassium bromate/cellulose mixture and the criteria for Packing Group I and II are not met. Group I 5.1: Liquid Any material which spontaneously ignites when mixed with cellulose in a 1:1 ratio; or

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.
n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
The charge is often composed of red phosphorus and strong oxidizer, such as potassium chlorate and potassium perchlorate. There are also party popper revolvers on the market, which use a Speedloader — style cartridge filled with six-party popper charges inserted into a normally colourful plastic device loosely resembling a pistol or revolver.

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. [74]
The oxidizer core is sodium chlorate (Na Cl O 3), which is mixed with less than 5 percent barium peroxide (Ba O 2) and less than 1 percent potassium perchlorate (K Cl O 4). The explosives in the percussion cap are a lead styphnate and tetrazene explosive mixture. The chemical reaction is exothermic and the exterior temperature of the generator ...
