[product use]：
Mainly used in the inorganic industry, it is the basic raw material for the manufacture of various potassium salts or bases, such as potassium hydroxide, potassium sulfate, potassium nitrate, potassium chlorate, potassium alum and so on.The pharmaceutical industry is used as a diuretic and a preventive medicine against potassium deficiency.The dyestuff industry is used to produce G salt, reactive dyes, etc.  In agriculture it is a potash fertilizer

It is also used in the manufacture of muzzle and muzzle flame retardants, steel heat treating agents, and in photography.It can also be used in medicine, scientific applications, food processing, and salt. Sodium chloride can be partially replaced by potassium chloride in order to reduce the possibility of hypertension.
