Product Description


100% water soluble noncaking white potassium nitrate powder used as fertilizer in







  POTASSIUM NITRATE is 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.

►History of production


From mineral sources


      The earliest known complete purification process for potassium nitrate was


outlined in 1270 by the chemist and engineer Hasan al-Rammah of Syria in his


book al-Furusiyya wa al-Manasib al-Harbiyya (The Book of Military Horsemanship


and Ingenious War Devices). In this book, al-Rammah describes first the


purification of barud (crude saltpeter mineral) by boiling it with minimal water and


using only the hot solution, then the use of potassium carbonate (in the form of


wood ashes) to remove calcium and magnesium by precipitation of their


carbonates from this solution, leaving a solution of purified potassium nitrate, which


could then be dried. This was used for the manufacture of gunpowder and


explosive devices. The terminology used by al-Rammah indicated a Chinese origin


for the gunpowder weapons about which he wrote.


At least as far back as 1845, Chilean saltpeter deposits were exploited in Chile and


California, USA.



From caves


    A major natural source of potassium nitrate was the deposits crystallizing from


cave walls and the accumulations of bat guano in caves. Extraction is


accomplished by immersing the guano in water for a day, filtering, and harvesting


the crystals in the filtered water. Traditionally, guano was the source used in Laos


for the manufacture of gunpowder for Bang Fai rockets.





     Perhaps the most exhaustive discussion of the production of this material is the


1862 LeConte text.He was writing with the express purpose of increasing


production in the Confederate States to support their needs during the American


Civil War. Since he was calling for the assistance of rural farming communities, the


descriptions and instructions are both simple and explicit. He details the "French


Method", along with several variations, as well as a "Swiss method". N.B. Many


references have been made to a method using only straw and urine, but there is no


such method in this work.



French method


     Niter-beds are prepared by mixing manure with either mortar or wood ashes,


common earth and organic materials such as straw to give porosity to a compost


pile typically 4 feet (1.2 m) high, 6 feet (1.8 m) wide, and 15 feet (4.6 m) long.The


heap was usually under a cover from the rain, kept moist with urine, turned often to


accelerate the decomposition, then finally leached with water after approximately


one year, to remove the soluble calcium nitrate which was then converted to


potassium nitrate by filtering through potash.


Swiss method


    LeConte describes a process using only urine and not dung, referring to it as the


Swiss method. Urine is collected directly, in a sandpit under a stable. The sand


itself is dug out and leached for nitrates which were then converted to potassium


nitrate using potash, as above.



From nitric acid



     From 1903 until the World War I era, potassium nitrate for black powder and


fertilizer was produced on an industrial scale from nitric acid produced using the


Birkeland–Eyde process, which used an electric arc to oxidize nitrogen from the air.


During World War I the newly industrialized Haber process (1913) was combined


with the Ostwald process after 1915, allowing Germany to produce nitric acid for


the war after being cut off from its supplies of mineral sodium nitrates from Chile.

























Water insoluble 





















      Potassium nitrate is used in fertilizers as a source of nitrogen and potassium –


two of the macronutrients for plants. When used by itself, it has an NPK rating of
