Technical Document

Brief overview

Potassium sulfate (K2SO4) is a white, crystalline salt that is soluble in water and non-flammable. It was formerly referred to as potassium sulphate in British English, sulphate of potash, arcanite, or potash of sulfur. This substance, which supplies potassium and sulfur, is frequently found in fertilizers.

Manufacturing Process

Making potassium sulfate follows a similar process to that of making sodium sulfate. Potassium sulfate can be made by reacting potassium chloride and sulfuric acid using the Leblanc process. Potassium sulfate is produced by the reaction that follows:

2KCl + H2SO4 → 2HCl + K2SO4

The raw materials utilized in the Hargreaves process to produce potassium sulfate are sulfur dioxide, oxygen, water, and potassium chloride. Hydrochloric acid dissolves. Sulfur dioxide (SO2) is produced when sulfur is burned.
