  2. Potassium nitrate - Wikipedia

    en.wikipedia.org/wiki/Potassium_nitrate

    Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O 3. It is an ionic salt of potassium ions K + and nitrate ions NO 3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). [ 5 ]

  3. Saltpetre works - Wikipedia

    en.wikipedia.org/wiki/Saltpetre_works

    A saltpetre works or nitrary[1] is a place of production of potassium nitrate or saltpetre used primarily for the manufacture of gunpowder. The saltpeter occurs naturally in certain places like the "Caves of Salnitre" (Collbató) known since the Neolithic. In the "Cova del Rat Penat", guano (bat excrements) deposited over thousands of years ...

  4. Curing salt - Wikipedia

    en.wikipedia.org/wiki/Curing_salt

    Another name for potassium nitrate (KNO 3), saltpetre, also called saltpeter or nitrate of potash, has been a common ingredient of some types of salted meat for centuries [5] but its use has been mostly discontinued due to inconsistent results compared to nitrite compounds (KNO 2, NaNO 2, NNaNO 2, etc.)

  5. Niter - Wikipedia

    en.wikipedia.org/wiki/Niter

    Niter or nitre [5] is the mineral form of potassium nitrate, KNO 3.It is a soft, white, highly soluble mineral found primarily in arid climates or cave deposits. Historically, the term niter was not well differentiated from natron, both of which have been very vaguely defined but generally refer to compounds of sodium or potassium joined with carbonate or nitrate ions.

  6. Rocket candy - Wikipedia

    en.wikipedia.org/wiki/Rocket_candy

    Rocket candy. Rocket candy, or R-Candy, is a type of rocket propellant for model rockets made with a form of sugar as a fuel, and containing an oxidizer. The propellant can be divided into three groups of components: the fuel, the oxidizer, and the (optional) additive (s). In the past, sucrose was most commonly used as fuel.

  7. Sodium nitrate - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrate

    Sodium nitrate is the chemical compound with the formula Na N O 3. This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter.

  8. Cordite - Wikipedia

    en.wikipedia.org/wiki/Cordite

    Gunpowder, an explosive mixture of sulfur, charcoal and potassium nitrate (also known as saltpeter), was the original propellant employed in firearms and fireworks.It was used from about the 10th or 11th century onward, but it had disadvantages, including the large amount of smoke it produced.

  9. Caliche - Wikipedia

    en.wikipedia.org/wiki/Caliche

    In the Atacama Desert in northern Chile, vast deposits of a mixture, also referred to as caliche, are composed of gypsum, sodium chloride and other salts, and sand, associated to salitre ("Chile saltpeter"). Salitre, in turn, is a composite of sodium nitrate (NaNO 3) and potassium nitrate (KNO 3).
