Magnesium Chloride

What is Magnesium Chloride?

Molecular Formula (Magnesium Chloride): MgCl

Molecular Weight: 95.21 g/mol

Chemical Name: Magnesium Chloride

CAS Number: 7786-30-3

It is a compound formed by the magnesium element with 2 chlorine ions, which are halogens. It has many areas of use as a magnesium source.

Hydrated (aqueous) and anhydrous forms are commercially available on the market. Salts of chlorinated compounds have conductivity when dissolved in water.

It is also known as chloromagnesite. It is one of the most abundant cations in the human body. It is also one of the most abundant cations within the cell.

It is mostly found naturally in salt waters. It is found in significant amounts especially in salt masses resulting from the evaporation of seawater.

Other Names Are As Follows;

• Magnesium Dichloride
• Chloromagnesite
• 6H20
• Anhydrous MgCl2
• Anhydrate
• Magnesium Salt

How is it Produced?

Magnesium Chloride production can be achieved through several methods. Among these, the most important one is its extraction from bromine in brine (salt water).

Another process is obtained from the reaction of Magnesium Hydroxide or Magnesium Oxide with Hydrochloric Acid. This reaction is as follows. This process is a regeneration process.

Water release occurs as a result of the reaction.

Mg(OH)₂ + 2HCl 》MgCl₂ + 2H₂O

It is a compound obtained as a by-product in titanium production.

What are the Physical and Chemical Properties?

It is in a white solid form in terms of physical appearance.

Melting point is 714 °C.

Boiling point is 1412 °C.

Density is 2.41 g/cm³.

Solubility in water is approximately 400 g/L at 20 °C. It has very good solubility in water. It also has solubility in alcohol.

It has highly hygroscopic properties. It absorbs moisture from the air.

What are the Usage Areas of Magnesium Chloride?

• It is the most important compound used in the production of magnesium metal.
• It is an important compound for erosion control.
• ‘Sorel Cement’ is produced by mixing magnesium oxide with this magnesium compound. The material produced in this way has a very hard structure.
• MgCl2 in liquid form is used to prevent dust formation on non-asphalt roads.
• It is a raw material used in the production of fireproof materials.
• It is a substance used in the production of skin care materials in the pharmaceutical and cosmetic sectors.
• It is used instead of Magnesium Sulfate and Magnesium Hydroxide in the production of some medicines. It has higher bioavailability than magnesium sulfate and magnesium oxide. It also does not require stomach acid to dissolve.
• It is used in the production of fire extinguishing chemicals.
• In antifreeze production, it further increases the effectiveness of Mono Ethylene Glycol and Mono Propylene Glycol compounds, which are the raw materials for antifreeze, and lowers the freezing point even further. For this reason, it is an additive in antifreeze production.
• It is used in paper manufacturing, refrigerated brines, and disinfectant manufacturing.
• It is purified from water by forming a chelated structure with EDTA.
• In the production of fire-resistant plywood, it is used together with Magnesium Oxide to ensure fire resistance. To make plywood fire-resistant, the resin used must contain flame retardant substances.

What are the Factors Affecting Prices?

Magnesium Chloride price is directly dependent on the prices of the materials used in its production. As the prices of Magnesium Hydroxide and Magnesium Oxide increase, the price of this chemical compound increases.

With the decrease in reserves in magnesium mines, magnesium chloride prices will rise.

As firms acting as Magnesium Chloride distributors decrease their stocks, the prices of this raw material will increase.
