Mainly used in the inorganic industry, it is the basic raw material for the manufacture of various potassium salts or alkalis such as potassium hydroxide, potassium sulfate, potassium nitrate, potassium chlorate, potassium alum, etc. It is used in the pharmaceutical industry as a diuretic and a drug for the prevention and treatment of potassium deficiency. The dye industry is used to produce G salts, reactive dyes, etc. In agriculture, it is a potash fertilizer. Its fertilizer effect is fast, and it is directly applied to farmland, which can make the moisture of the lower layer of soil rise, and has the effect of drought resistance. However, it is not suitable for application in saline-alkali land and on tobacco, sweet potato, sugar beet and other crops. Potassium chloride tastes similar to sodium chloride (bitter) and is also used as an additive to low-sodium salts or mineral water. In addition, it is used in the manufacture of flame suppressants for muzzles or muzzles, heat treatment agents for steel, and for photography. It can also be used in medicine, scientific applications, food processing, and salt can also be partially replaced with potassium chloride to reduce the possibility of high blood pressure.
