Mainly used in inorganic industry, it is the basic raw material for producing various potassium salts or bases such as potassium hydroxide, potassium sulfate, potassium nitrate, potassium chlorate and potassium dichromate.
Pharmaceutical industry is used as diuretics and drugs to prevent and treat potassium deficiency. Dye industry is used to produce G salt, reactive dyes and so on. Agriculture is a kind of potash fertilizer. Its fertilizer efficiency is fast, and when it is directly applied to farmland, it can increase the moisture of the lower soil and has the effect of drought resistance. But it is not suitable for saline-alkali land and crops such as tobacco, sweet potato and beet. The taste of potassium chloride is similar to that of sodium chloride (bitter), and it is also used as an additive of low sodium salt or mineral water. In addition, it is also used to make muzzle or muzzle flame retardant, steel heat treatment agent and photography. It can also be used in medicine, scientific application and food processing, and part of potassium chloride can be used to replace sodium chloride in salt, thus reducing the possibility of hypertension.
The chemical formula of potassium chloride is KCl, which is a colorless elongated rhombic or cubic crystal, or a white crystalline powder with small particles. It looks like salt, tasteless and salty. Additives commonly used in low sodium salt and mineral water. Potassium chloride is a commonly used electrolyte balance regulator in clinic, which has definite clinical effect and is widely used in clinical departments.
