Potassium sulfate is the inorganic compound with formula K2SO4. It is a white water-soluble solid. It is commonly used in fertilizers, providing both potassium and a source of sulfur.Many of us take pills or other supplements to help us get important nutrients like vitamins, minerals, and proteins. We need these compounds to help us grow, repair damaged tissue, or simply function in the first place. All living things are like that. This means plants also need to take their vitamins, so to speak, and some of the nutrients plants need include potassium and sulfur.
Potassium sulfate molecular formula is K2SO4 or K2O4S
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 can also be used in pyrotechnics in combination with potassium nitrate to generate a purple flame.
