►Description 

 

  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.

 

 

LeConte

 

     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.
