Basic Copper Sulphate is an inorganic salt with the chemical formula KSO. Generally, the content of k is 50%-52%, and the content of s is about 18%.
Pure potassium sulfate is a colorless crystal, and agricultural potassium sulfate is light yellow in appearance. Potassium sulfate has low hygroscopicity, is not easy to agglomerate, has excellent physical properties, and is easy to apply. It is a good water-soluble potassium fertilizer. Potassium sulfate is especially suitable for economic crops that do not contain chlorine and potassium, such as tobacco, grapes, sugar beets, tea trees, potatoes, flax and various fruit trees. It is also the main raw material for making chlorine-free nitrogen, phosphorus and potassium ternary compound fertilizer. Potassium sulfate is a chemically neutral and physiologically acidic fertilizer, suitable for all kinds of soil (excluding flooded soil) and crops. After potassium ions are applied to the soil, they can be directly absorbed by crops and absorbed by soil colloids. In sulfur-deficient soils, it is best to apply potassium sulfate to cruciferous crops and other crops that require more sulfur.
It is mainly used for the biochemical test of serum protein, the preparation of Kjeldahl nitrogen catalyst, other potassium salts, fertilizers, medicines, glass, alum, etc. It is the root material for making potassium carbonate, potassium persulfate and other potassium salts. The glass industry is used as a scavenger. The dye industry serves as an intermediate. The perfume industry is used as an auxiliary. The pharmaceutical industry is also used as a laxative to treat soluble barium salt poisoning. Potassium sulfate is a commonly used potassium fertilizer in agriculture. The potassium oxide content is 50%, and it is commonly known as "white kali" in Taiwan. In addition, Copper Chloride Dihydrate Manufacturers' potassium sulfate is also used in glass, dyes, perfumes, medicine, etc.
