  2. Potassium perchlorate - Wikipedia

    en.wikipedia.org/wiki/Potassium_perchlorate

    Treatment of thyrotoxicosis (including Graves' disease) with 600-2,000 mg potassium perchlorate (430-1,400 mg perchlorate) daily for periods of several months, or longer, was once a common practice, particularly in Europe, [10] [12] and perchlorate use at lower doses to treat thyroid problems continues to this day. [13]

  3. Chemical oxygen generator - Wikipedia

    en.wikipedia.org/wiki/Chemical_oxygen_generator

    A chlorate candle, or an oxygen candle, is a cylindrical chemical oxygen generator that contains a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,100 °F), producing sodium chloride, iron oxide, and oxygen at a fixed rate of about 6.5 man-hours per kilogram of the mixture. The mixture has an indefinite ...

    en.wikipedia.org/wiki/Pyrotechnic_composition

    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 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]

  6. Pyrotechnic initiator - Wikipedia

    en.wikipedia.org/wiki/Pyrotechnic_initiator

    One of the most common initiators is ZPP, or zirconium – potassium perchlorate – a mixture of metallic zirconium and potassium perchlorate. This mixture is used in the NASA Standard Initiator , [ 2 ] which is used to ignite various pyrotechnic systems, including the NASA standard detonator . [ 3 ]

  7. Flash powder - Wikipedia

    en.wikipedia.org/wiki/Flash_powder

    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.
