Usage and purpose



It is the basic raw material for manufacturing various potassium salts such as potassium carbonate and potassium persulfate. The glass industry is used as a settling agent. The dye industry is used as an intermediate. Used as additives in the spice industry. The pharmaceutical industry is also used as a laxative and in the treatment of soluble barium salt poisoning. Potassium sulfate is a commonly used potassium fertilizer in agriculture, with a potassium oxide content of 50%, commonly known as "Baikali" in Taiwan. In addition, potassium sulfate is also used in industry for glass, dyes, spices, pharmaceuticals, and more.



Agricultural applications



Potassium sulfate is a colorless crystal with low hygroscopicity and is not prone to clumping. It has good physical properties and is easy to apply, making it a good water-soluble potassium fertilizer. Potassium sulfate is also a chemically neutral and physiologically acidic fertilizer. Potassium sulfate is a chlorine free, high-quality, and efficient potassium fertilizer, especially in the cultivation of chlorine sensitive crops such as tobacco, grapes, sugar beets, tea trees, potatoes, flax, and various fruit trees. It is an indispensable and important fertilizer; It is also the main raw material for high-quality nitrogen, phosphorus, and potassium ternary compound fertilizers.



Potassium sulfate type compound fertilizer is produced using potassium chloride low-temperature conversion, chemical synthesis, and spray granulation processes. It has good stability and contains not only the three essential nutrients of N, P, and K for plants, but also medium and trace elements such as S, Ca, Mg, Zn, Fe, and Cu. This fertilizer is suitable for various economic crops, especially chlorine sensitive crops. The main components of potassium sulfate type compound fertilizer include MAP (monoammonium phosphate) DAP (diammonium phosphate), and ammonium sulfate (mainly obtained by neutralizing excess sulfuric acid from low-temperature conversion with gas ammonia). Potassium sulfate, urea, and other small amounts of impurities such as calcium sulfate, iron, aluminum, magnesium salts of phosphate, and trace amounts of unreacted potassium chloride.
