potassium chloride

Product Character
Chemical formula:KCl, molecular weight: 74.5513.
Appearance:White crystal or powder. Melting point: 770? 
Specific gravity: 1.98 g/cm3.  soluble in water. non-poisonous. 
Application: Potassium chloride (KCl) is a metal halide salt that is used in avariety of areas. The dominant application of potassium chloride is to serve as a fertilizer, which offers potassium to plants and prevents them from certain diseases. Besides, it can be applied in food and medical industry. As a treatment for hypokalemia, potassium chloride pills are taken to balance the blood's potassium levels and prevent potassium deficiency in the blood. In food industry, it serves as a electrolyte replenisher and a good salt substitute for food, as well as a firming agent to give consistent texture to food, thus to strengthen its structure.

Packing:In PP woven bag with PE bag inside,25kg or 50kg/bag.
