Chemical Properties:

  1. Potassium sulfate,K2804, also known as salt of Lemery and arcanite, is a colorless crystalline solid that melts at 1072°C(1960 OF). Potassium sulfate is soluble in water,but insoluble in alcohol. Potassium sulfate is used in manufacturing glass, aluminum, fertilizers, and in medicine.
  2. Potassium sulfate, sulfate of potash, K2SO4, white solid, soluble. Common constituent of potassium salt minerals.


  1. Technical grades are used in fertilizers for manufacture of potassium alum, potassium carbonate and glass; the reagent grade is used in the Kjeldahl determination of nitrogen.
  2. potassium sulfate is a reagent in cosmetics. Potassium sulfate is an inorganic salt with a primary function as a viscosity-increasing agent.
  3. Potassium Sulfate is a flavoring agent that occurs naturally, consisting of colorless or white crystals or crystalline powder having a bitter, saline taste. it is prepared by the neutralization of sulfuric acid with potassium hydroxide or potassium carbonate.
  4. Potassium sulfate is used as chemical fertilizer, which can make economic plants achieve sustainable high quality and high yield. Potassium sulfate is used in tea, vegetables, fruits and other crops
  5. Potassium sulfate is used as an analytical reagent (such as the determination of nitrogen), as well as in the synthesis of potassium salts and the pharmaceutical industry
