The differences between Magnesium Chloride Anhydrous and Magnesium Chloride Hexahydrate

Magnesium Chloride is a common chemical raw material in chemical industry. Magnesium Chloride on the market is mainly Magnesium Chloride Anhydrous and Magnesium Chloride Hexahydrate, then what are the differences between Magnesium Chloride Hexahydrate and Magnesium Chloride Anhydrous?
The differences between Magnesium Chloride Anhydrous and Magnesium Chloride Hexahydrate are mainly in appearance, crystal water, deliquescence,title in industry, production technology and applications. The specific differences are as follows:

1.Appearance: Magnesium Chloride Hexahydrate usually appears as a colorless crystal, while Magnesium Chloride Anhydrous is a white hexagonal crystal with luster.

2.Crystal water: Magnesium Chloride Hexahydrate and Magnesium Chloride Anhydrous differ in crystal water. Magnesium Chloride Hexahydrate contains six molecules of crystal water, with the formula MgCl2·6H2O. Magnesium Chloride Anhydrous does not contain crystal water, with the formula MgCl2.

3.Deliquescence: Magnesium Chloride Hexahydrate is prone to deliquescence in humid air, while the solubility of Magnesium Chloride Anhydrous is higher than that of Magnesium Chloride Hexahydrate .

4.Title in industry: Magnesium Chloride Anhydrous is commonly referred to as “powdered salt,”while Magnesium Chloride Hexahydrate is usually referred to as “halide crystal” .

5.Production technology: Magnesium Chloride Hexahydrate is typically produced by evaporating and concentrating from the mother liquor- a solution of unsaturated Magnesium Chloride after bromine production , while Magnesium Chloride Anhydrous can be produced by dehydration of a mixture of Ammonium Chloride and Magnesium Chloride Hexahydrate or can be produced by dehydration in a hydrogen Chloride stream or a complex salt of Ammonium Chloride and Magnesium Chloride Hexahydrate .

6.Applications: Magnesium Chloride Hexahydrate can be used in the food industry, construction materials industry, cement industry, deicing agents, desiccants, animal husbandry and aquaculture, pulp and paper making, Magnesium fertilizers, and wastewater treatment. Magnesium Chloride Anhydrous is mainly used in the metallurgical, light industry, coal, construction, chemical and other industries.
