Product Description
Potassium sulfate, with the chemical formula K2SO4, is an inorganic compound with many uses. The following are the uses of potassium sulfate, including:
- Agricultural Uses:
- Potassium sulfate is an effective potassium fertilizer used primarily to supplement potassium in the soil, enhancing crop yield and quality.
- It is suitable for various soil types, particularly neutral and alkaline soils, where it significantly improves soil fertility. In sandy loam or red earth, its application significantly enhances soil fertility.
- Potassium sulfate fertilizer rapidly replenishes potassium essential for crop growth, especially in sweet potatoes, potatoes, watermelons, tobacco, and greenhouse fruits and vegetables. It not only boosts crop growth but also enhances flavor.
- Potassium sulfate enhances crops' stress resistance and cold tolerance, strengthens plants, and combats soil salinization.
- Industrial Uses:
- In industry, potassium sulfate is used to produce various chemicals such as potassium aluminum sulfate, potassium chromium sulfate, and potassium iron sulfate.
- It serves as an auxiliary material in glass and ceramic manufacturing and as a raw material for producing paper, fibers, and abrasives.
- In the dye industry, potassium sulfate acts as an intermediate, while in the fragrance industry, it functions as an additive.
- Medical Uses:
- Potassium sulfate also finds applications in the medical field, particularly in the preparation of certain medications, notably antipyretics and anti-inflammatory drugs.
- It regulates potassium ion levels in the body, preventing and treating potassium deficiency.
- Other Applications:
- Potassium sulfate is utilized in electrolytes, petroleum refining, water treatment, and mineral extraction.
- In the food industry, it serves as a general additive. In analytical testing, it is used for serum protein biochemical assays.
