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).
Pyrodex is similar in composition to black powder (which consists of potassium nitrate, charcoal, and sulfur) [5] but incorporates several other compounds: [6] [7] 45% potassium nitrate; 9% charcoal; 6% sulfur; 19% potassium perchlorate; 11% sodium benzoate; 6% dicyandiamide; 4% dextrin; 1% water
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.
potassium permanganate with antimony, very slow; Manganese Delay Composition: manganese with lead chromate and barium chromate (lead chromate is the principal oxidizer, barium chromate acts as burning rate modifier, the more of it the slower the reaction) [1] Tungsten Delay Composition: tungsten with barium chromate and potassium perchlorate [2]
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
It is desired that the pyrotechnic source be gasless. The standard heat source typically consist of mixtures of iron powder and potassium perchlorate in weight ratios of typically 88/12, 86/14, and 84/16. The higher the potassium perchlorate level, the higher the heat output (nominally 200, 259, and 297 calories/gram, respectively).
