potassium perchlorate การใช้

• "' Potassium perchlorate "'is the inorganic flash compositions, stars, and sparklers.
• Common oxidizers used are potassium perchlorate and potassium nitrate.
• Early formulations used potassium chlorate instead of potassium perchlorate.
• Flash compositions used in firecrackers usually consist of a mixture of aluminium powder and potassium perchlorate.
• Other explosives used in primers can include lead azide, potassium perchlorate, or diazodinitrophenol ( DDNP ).
• Common whistle fuels contain Benzoate or Salicylate compounds and a suitable oxidizer such as Potassium Perchlorate.
• The plant had used potassium perchlorate as one of the ingredients during its 40 years of operation.
• The charge is often composed of red phosphorus and strong oxidizer, such as potassium chlorate and potassium perchlorate.
• As an oxidizer, potassium perchlorate can be used safely in the presence of sulfur, whereas potassium chlorate cannot.
• Different varieties of flash powder are made from different compositions; most common are potassium perchlorate and aluminium powder.
• The filling was a mixture of black powder, barium nitrate, and potassium perchlorate, and does not require a detonator.
• A typical whistle mix is made from 70 % potassium perchlorate and 30 % sodium benzoate, measured by weight.
• Earlier forms of the detonator employed a vial of sulfuric acid surrounded by a mixture of potassium perchlorate and sugar.
• Potassium perchlorate and other metal perchlorates generate smoke as the metal chlorides are solid materials creating aerosols of their particles.
• An example composition is boron, potassium perchlorate, sodium salicylate, iron carbonate or magnesium carbonate ( as combustion retardant ), and binder.
• Except for potassium perchlorate, perchlorate salts are soluble in water and dissociate into the perchlorate anion and the cation from the salt.
• The higher the potassium perchlorate level, the higher the heat output ( nominally 200, 259, and 297 calories / gram, respectively ).
• During this time, NCR branched out into making composite motors based on potassium perchlorate that would produce a pink flame during the burn.
• Although not stoichiometrically balanced, a ratio of seven parts potassium perchlorate to three parts dark pyro aluminium is the composition used by most pyrotechnicians.
• Most perchlorate compounds, especially salts of electropositive metals such as sodium perchlorate or potassium perchlorate, are inert and are slow to react with organic compounds.
