Magnesium chloride

Magnesium chloride is a white, crystalline solid at room temperature, typically odorless and highly hygroscopic, with a melting point of approximately 714 °C and decomposing before boiling. It is an inorganic ionic compound and a source of magnesium ions in aqueous and molten forms. Magnesium chloride serves as a key precursor in the production of metallic magnesium via electrolysis and is widely used as a coagulant in tofu manufacturing, a dust suppressant on roads, and a component in de-icing formulations. It is also employed in the synthesis of catalysts, specialty ceramics, and as a magnesium source in pharmaceutical and nutraceutical preparations. Typical application areas include metallurgy, food processing, construction materials, and water treatment.


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.
