Description
Magnesium chloride 6AQ, or magnesium chloride hexahydrate, is an inorganic salt consisting of magnesium chloride with six water molecules. It is a white to Colorless crystalline material that is highly Hygroscopic. The product is mainly extracted from natural brine sources and seawater, where it is often supplied in flake or pellet form. Because of its excellent solubility in water and chemical stability, Magnesium Chloride 6AQ is widely used in industry, construction, agriculture and road management.

Applications
Magnesium chloride 6AQ is applied in various ways, for instance:
1. Chemical Industry
It is used as a starting material for the production of magnesium compounds, such as magnesium oxide and magnesium hydroxide, and as a raw material for the production of magnesium metals.
2. Agriculture
It is used in soil tillage to correct magnesium deficiencies.
3. Construction
It is essential in the manufacture of Sorel cement (magnesium cement), which is used in fire-resistant and lightweight building materials.
4. Water Treatment
Used as a coagulant and flocculant in wastewater and drinking water treatment.
5. Road Management
Used as a dust binder and road salt for ice control on roads and unpaved areas.
