Uses:
Magnesium chloride is used for a variety of other applications besides the production of Mg metal. It is used in the manufacture of textiles, paper, fireproofing agents, cements and refrigeration brine. It has also been used in dust and erosion control. Mixed with hydrated magnesium oxide, magnesium chloride forms a hard material called "Sorel-cement". The cement is a mixture of MgO (burnt magnesia) with MgCl2 with the approximate chemical formula Mg4Cl2(OH)6(H2O)8, corresponding to a weight ratio of 2.5-3.5 parts MgO to one part MgCl2. This usage of magnesium chloride is unmatched by any other compound. MgCl2 was one of the earlier antiseptics, first used for that purpose by Dr Pierre Delbert in 1915. One veterinary study in 1989 indicated some effectiveness against tumors when used as a feed additive.
A commercial form of liquid MgCl2 called DustGard Liquid is used to control dust on unpaved roads, construction sites and similar surfaces. Because it is produced from naturally occurring minerals, it improves air quality and visibility with minimal environmental impact. It also decreases vehicle maintenance costs, prevents soil erosion and reduces the need for blading, watering and gravel replacement.
Chemical Properties: Magnesium is an essential nutrient for plants and animals and is a natural constituent of fruits, vegetables, grain, meats and sea-foods. It is the fourth most abundant cation in the human body and the second most plentiful intracellularly. The average 60-kg human adult body contains about 24 g magnesium of which about one-half resides in bone. Although plasma levels vary between 1.7 and 3.0 mg per dl, very little is contained in extracellular fluid. Magnesium is essential for the production and transfer of energy, for protein, fat, and nucleic acid synthesis, for contractility in muscle and excitability in nerve, and for the activity of numerous enzyme systems
