Beschreibung
Potassium nitrate is a solid, colorless, crystalline ionic compound that exists as the mineral niter.Potassium nitrate is also known as saltpeter. The name saltpeter comes from the Latin sal petrae, meaning salt of stone or salt of Petra. he term saltpeter or Chilean saltpeter is also used for sodium nitrate, NaNO3.
Chemische Eigenschaften
Also known as niter,KN03 is flammable, water-soluble, white crystals with saline taste that melt at 337°C. Used in pyrotechnics, explosives, and matches, as a fertilizer, and as an analytical reagent.
Chemische Eigenschaften
Potassium nitrate is an odorless, white or colorless crystalline powder with a salty, taste.
History
Saltpeter’s most prominent use in human history is as the principal ingredient in gunpowder.The potassium nitrate used in gunpowder was originally obtained from natural mineral deposits of niter. Small quantities formed as efflorescence deposits on damp stone walls were identified as early as 2000 b.c.e. in Sumerian writings. As the use of black powder expanded with the development of weapons, the demand for saltpeter exceeded supply. This was exacerbated during times of war. To meet the demand for saltpeter to produce black powder, a saltpeter industry developed that followed prescribed methods to produce large quantities of saltpeter. The method depended on processing dirt obtained from areas where nitrates would naturally form. These were areas in which animal waste had accumulated such as the dirt floors of barns, stables, herding pens, caves, or cellars. The ammonia compounds in the urine and fecal wastes in these areas underwent nitrifi cation to produce nitrates, which combined with potassium in the soil to form saltpeter.
Verwenden
Although the most prominent use of saltpeter is for the production of black powder,potassium nitrate is also used as fertilizer. In the first half of the 17th century, JohannRudolf Glauber (1604–1668) obtained saltpeter from animal pens and discovered its useto promote plant growth. Glauber included saltpeter with other nutrients in fertilizer mixtures. Glauber’s work was one of the first to indicate the importance of nutrient cyclingin plant nutrition.
Verwenden
Potassium Nitrate is a preservative and color fixative in meats which exists as colorless prisms or white granules or powder. it has a solubility of 1 g in 3 ml of water at 25°c. see nitrate.
Verwenden
In fireworks, fluxes, pickling meats; production of nitric acid; manufacture of glass, matches, gunpowder; freezing mixtures. Agricultural fertilizer. Preservative in foods. In dentrifices to reduce tooth hypersensitivity.
Verwenden
This natural substance is the product of the decomposition of lime and urine. The white granules or powder are soluble in water 1:3 but insoluble in alcohol. Potassium nitrate, also called saltpeter or nitre, was combined with sulfuric acid to nitrate cotton for the manufacture of collodion. It was also used with magnesium to make flash powder and added to ferrous sulfate developers to produced cool white tones in collodion positives.

Weltgesundheitsorganisation (WHO)
Potassium nitrate was formerly used as a diuretic. Its use for this purpose is now considered obsolete but it is still available in at least one country for the correction of potassium deficiency. It is aslo widely permitted at concentrations of the order of 5% in proprietary toothpastes. In some countries the drug has been banned due to a potential carcinogenic risk arising from the excessive use of nitrates and their transformation to nitrosamines.
Allgemeine Beschreibung
A white to dirty gray crystalline solid. Water soluble. Noncombustible, but accelerates the burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen are produced in fires. Used in solid propellants, explosives, fertilizers.
Air & Water Reaktionen
Soluble in water.
Reaktivität anzeigen
Potassium nitrate mixed with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. Powdered antimony mixed with Potassium nitrate explodes when heated [Mellor 9:282 1946-47]. A mixture of antimony trisulfide and Potassium nitrate explodes at a red heat [Mellor 9:524. 1946-47]. Arsenic disulfide forms explosive mixtures when mixed with Potassium nitrate, [Mellor 9:270.1946-47]. A mixture of sodium acetate and Potassium nitrate may cause an explosion [Pieters 1957. p. 30]. A mixture of Potassium nitrate and sodium hypophosphite constitutes a powerful explosive [Mellor 8:881. 1946-47]. A mixture of powdered zirconium and Potassium nitrate explodes when heated above the melting point [Mellor 7:116. 1946-47].
Hazard
Dangerous fire and explosion risk when shocked or heated, or in contact with organic mate- rials, strong oxidizing agent.
Health Hazard
Exposure can cause mild irritation of eyes, nose and throat.
Landwirtschaftliche Anwendung
Commercial potassium nitrate (KNO3) is known as nitre or saltpeter. It contains about 46% potassium, as K2O. Nitre is commonly found in small amounts, as a surface efflorescence in arid regions, in caves and other sheltered places. Nitre is associated with soda nitre in the desert regions of Chile, Italy, Egypt and the USA.
Landwirtschaftliche Anwendung
It is a potassium salt of nitric acid. Potassium nitrate (KNO3), also known as saltpeter or nitrate of potash, is a white crystalline salt which occurs naturally in nitre or saltpeter. It is a useful fertilizer for normal application and fertigation. Potassium (44% K2O) and nitrogen (13 %) are the constituents of NK fertilizers, which serve as a source of potassium, where extra chloride is not desired.
The agricultural grade of potassium nitrate is freeflowing and non-caking, with a particle size in the range of 1500 to 400 microns.
Potassium nitrate, which is slightly hygroscopic and granulated, can be spread on soil by trucks, fertilizer distributors or by aerial spraying. In a mixed fertilizer, a powdered grade of nitrate of potash does not cake. Potassium nitrate is made by the reaction of potassium chloride with nitric acid as:
The nitrate of potash forms an easily breakable crust on top. It is chemically neutral and its nitrogen and potassium oxide ratio is roughly 1:3. It has been used successfully as a source of nitrogen and potassium for tobacco, tomato, potato, corn, citrus and carnations.
Landwirtschaftliche Anwendung
Saltpeter is another name for potassium nitrate, a white crystalline salty substance used in preserving meat and as a constituent of gun powder. It provides both potassium and nitrogen and is used as a fertilizer.
Industrielle Verwendung
Potassium nitrate is also called niter and saltpeter,although these usually refer to the nativemineral. A substance of the composition KNO3,it is used in explosives, for bluing steel, and infertilizers. A mixture of potassium nitrate andsodium nitrate is used for steel-tempering baths.The mixture melts at 250°C. Potassium nitrateis made by the action of potassium chloride onsodium nitrate. It occurs in colorless prismaticcrystals, or as a crystalline white powder. It hasa sharp saline taste and is soluble in water. Thespecific gravity is 2.1 and the melting point is337°C.
Potassium nitrate contains a large percentageof oxygen, which is readily given up andis well adapted for pyrotechnic compounds. Itgives a beautiful violet flame in burning. It isused in flares and in signal rockets.
Most enamels contain some oxidizing agentin the form of potassium or sodium nitrate.Only a small amount of nitrate is necessary; 2to 4% is sufficient to maintain oxidizing conditionsin most smelting operations.
In glazes it is sometimes used as a flux inplace of potassium oxide, but, owing to its costand solubility, very little of it is contained inglaze. Where conditions prevent the use of sufficientpotash feldspar, potassium oxide is introducedinto the mix, usually in the form of thenitrate in a frit.
Potassium nitrite is a solid of the compositionKNO2 used as a rust inhibitor, for theregeneration of heat-transfer salts, and for themanufacture of dyes.
