Potassium chloride is an inorganic ionic compound. It appears as white crystals, granules or powder, odorless and salty in taste, non-hygroscopic, stable at room temperature, with neutral aqueous solution (pH 5.5~8.0), low toxicity and good solubility in water. It is an important source of potassium.

1. Agriculture (largest consumption, accounting for more than 70%): Used in the production of potassium fertilizers to promote crop photosynthesis, enhance stress resistance, and improve crop yield and quality. Suitable for field crops such as rice, wheat and corn. Use with caution on chlorine-sensitive crops (tobacco, potato, grape, etc.).
2. Industry: Used in the manufacture of potassium salts such as potassium hydroxide, potassium sulfate, potassium nitrate and potassium chlorate; applied in metal heat treatment salt baths, welding fluxes, electrolytic raw materials for magnesium smelting; also used in dyes, electroplating, flame suppressants, etc.
3. Pharmaceutical: Used as a diuretic and electrolyte replenisher for the prevention and treatment of hypokalemia.
4. Food: Used as a nutritional supplement, salt substitute and gelling agent in the production of low-sodium foods.
5. Scientific Research: Used as an analytical reagent, for buffer solution preparation, as a primary standard substance, and a raw material for culture media, etc.
