[Description]

Potassium sulfate (K2SO4) is a kind of chemical compounds that is commonly used in agriculture. The dominant application of potassium sulfate is as a fertilizer, which is commonly applied to offer both potassium and sulfur, thus improving the quality and yield of crops growing in soils that lack an adequate supply of this essential elements. Besides, the crude potassium sulfate is sometimes employed in the production of glass. It also has applications in other industries, which is used as a flash reducer in artillery propellant charges and as an alternative blast media similar to soda in the process of soda blasting.
