SULPHATE OF POTASH
[CODE NO. 3284]

Potassium sulfate (K2SO4) (in British English potassium sulphate, also called sulphate of potash, arcanite, or archaically known as potash of sulfur) is a non-flammable white crystalline salt which is soluble in water. The chemical compound is commonly used in fertilizers, providing both potassium and sulfur.

When potassium sulfate is heated in water and subjected to swirling in a beaker, the crystals form a multi-arm spiral tructure when allowed to settle. Potassium sulfate could be used to study spiral structures in the laboratory.

Two crystalline forms are known. Orthorhombic ß-K2SO4 is the common form, but it converts to a-K2SO4 above 583°C. These structures are complex, although the sulfate adopts the typical tetrahedral geometry.

It does not form a hydrate, unlike sodium sulfate. The salt crystallize as double six-sided pyramids, classified as rhombic. They are transparent, very hard and have a bitter, salty taste. The salt is soluble in water, but insoluble in solutions of potassium hydroxide (sp. gr. 1.35), or in absolute ethanol.

The dominant use of potassium sulfate is as a fertilizer. K2SO4 does not contain chloride, which can be harmful to some crops. Potassium sulfate is preferred for these crops, which include tobacco and some fruits and vegetables. Crops that are less sensitive may still require potassium sulfate for optimal growth if the soil accumulates chloride from irrigation water.

The crude salt is also used occasionally in the manufacture of glass. Potassium sulfate is also used as a flash reducer in artillery propellant charges. It reduces muzzle flash, flareback and blast overpressure.

It is sometimes used as an alternative blast media similar to soda in soda blasting as it is harder and similarly water-soluble.

Potassium sulfate (K2SO4) mineral name arcanite forms colorless, no hygroscopic crystal. It occasionally occurs in nature in the pure state in salt deposit, but is more widely found in the form of mineral double salts in  combination  with sulfates of calcium, magnesium, and sodium.

Potassium sulfate is after potassium chloride the most important potassium containing fertilizer being used mainly for special crops. Potassium sulfate constitutes 5%  of  the  world demand for potash fertilizer.

Prior to 1939, the German potash industry  was  the  chief source of potassium sulfate for American chemical and  fertilizer industries, although considerable tonnages were being produced in this  country  by  the  interaction  of potassium chloride and sulfuric acid as a side product of salt-cake  manufacture.  With the termination of European imports, the production of the salt was undertaken on a larger scale by the American Potash and Chemical Corp.  through the interaction of burkeite  (Na2CO3 2Na2SO4)  with  potassium  chloride  followed  in  turn  by   the successful  recovery  of  this  salt  from  langbeinite  by   the International  Minerals  and Chemical Corp. In  agricultural  use potassium  sulfate  is  preferred for the  tobacco  crop  of  the Southeast and the citrus crop of Southern California.
