Briefing
Potassium sulfate (K2SO4) is the chemical compound is commonly used in fertilizers, providing both potassium and sulfur.
Detailed
Potassium Sulphate Crystalline Powder
Potassium sulfate (K2SO4) 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.
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.
