Magnesium chloride is the name for the chemical compound with the formula MgCl2 and its various hydrates MgCl2(H2O)x. These salts are typical ionic halides, being highly soluble in water.
Chemical formula：MgCl2
Molar mass：95.211 g/mol (anhydrous)/203.31 g/mol (hexahydrate)
Appearance：white or colourless crystalline solid
Density：2.32 g/cm3 (anhydrous)/1.569 g/cm3 (hexahydrate)
Melting point：714 °C (1,317 °F; 987 K) 117 °C (243 °F; 390 K) (hexahydrate) on rapid heating: slow heating leads to decomposition from 300 °C (572 °F; 573 K)
Boiling point：1,412 °C (2,574 °F; 1,685 K)
Solubility in water：anhydrous 52.9 g/100 mL (0 °C)/54.3 g/100 mL (20 °C)/72.6 g/100 mL (100 °C)
hexahydrate 235 g/100 mL (20 °C)
Solubility：slightly soluble in acetone, pyridine/Solubility in ethanol 7.4 g/100 mL (30 °C)
De-icing and Snow Removal: Magnesium chloride is commonly used as a de-icing agent for roads, highways, and walkways during winter months. It works effectively in lower temperatures than sodium chloride (NaCl) and is less corrosive to vehicles and infrastructure.
Magnesium Production: MgCl₂ is a key intermediate in the production of metallic magnesium. It is produced from seawater or brines and then electrolyzed to produce magnesium metal in a process known as the Dow process or electrolysis of molten MgCl₂.
Water Treatment: Magnesium chloride is used in water purification processes, particularly in removing contaminants from water through coagulation or flocculation.
Pharmaceutical and Medical Applications: Magnesium chloride is sometimes used in the treatment of magnesium deficiency. It can also be found in oral supplements and is used in some medical formulations for its laxative and antacid properties.
Food Industry: In food, magnesium chloride (sometimes referred to as E511) is used as a food additive, often as a coagulant in tofu production or as a firming agent in pickles.
Dust Control: Magnesium chloride is used in road dust suppression and soil stabilization, especially in areas where water conservation is a concern, as it helps bind dust particles to the surface and reduces airborne dust.
Battery and Energy Storage: Magnesium chloride is also under investigation for use in magnesium-ion batteries, which are a promising alternative to lithium-ion batteries due to magnesium’s abundance, safety, and energy density.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo.
