Product Description
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 is commonly used in fertilizers, providing both potassium and sulfur.
Manufacture:-
The process for manufacturing potassium sulfate is similar to that used for the manufacture of sodium sulfate.
Potassium sulfate can be synthesised by reaction of potassium chloride with sulfuric acid according to the Leblanc process. Potassium sulfate is produced according to the following reaction:
2 KCl + H2SO4 → 2 HCl + K2SO4
The Hargreaves process uses sulfur dioxide, oxygen and water and potassium chloride as the starting materials to produce potassium sulfate. Hydrochloric acid evaporates off. SO2 is produced through the burning of sulfur.

Uses:-
The principal 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.
Sometimes used as an alternative blast media similar to soda in soda blasting as it is harder and similarly water soluble.
Photographic industry as a photographic fixative.
The paper industry for pulp bleaching agent after dechlorination.
Bleached cotton printing and dyeing industry as a dechlorination agent.
In medicine as a detergent, disinfectant, a laxative.
The food industry used as chelating agents, antioxidants.
