Magnesium Chloride
Magnesium Chloride is a highly versatile, naturally occurring inorganic compound widely valued for its solubility, stability, and broad industrial utility.
CAS # 14989-29-8
Magnesium chloride is commonly derived from seawater or brine sources through solar evaporation. Its exceptional hygroscopicity and compatibility with various chemical processes makes it a preferred option across manufacturing, environmental, agricultural, and specialty applications. Known for its effectiveness as a de-icer, dust suppressant, and nutritional supplement, this highly soluble compound offers superior performance with reduced environmental impact compared to many alternatives.
General Properties
Chemical Formula: MgCl₂
Appearance: White or off-white flakes, pellets, or powder
Solubility: Highly soluble in water and alcohol
Melting Point: 714°C (anhydrous)
Applications
De-Icing & Anti-Icing
Magnesium Chloride lowers the freezing point of water effectively and performs at lower temperatures compared to sodium-based salts.
Dust Control & Soil Stabilization
Attracts and retains moisture, reducing airborne dust and makes it ideal for unpaved roads, construction sites, mining operations, and agricultural paths
Industrial & Chemical Manufacturing
Used in the production of magnesium metal, magnesium salts, and textile processing.
Agriculture
Used in fertilizer blends to enhance plant growth, chlorophyll formation, and nutrient absorption.
Oil and Gas Industry
In petroleum applications, magnesium chloride is used in drilling fluids to control shale hydration, increase fluid density, and stabilize wellbores.
Water Treatment
Effective as a coagulant aid for improving clarity and impurity removal in municipal and industrial water systems
Advantages
High Performance in Harsh Environments: Works effectively for de-icing at lower temperatures than standard rock salt and maintains performance even in high-moisture conditions.
Environmentally Considerate: It has lower chloride release compared to some alternatives and is less corrosive to metal surfaces, vehicles, and concrete when used properly.
Cost Efficiency: Requires smaller application amounts for dust suppression and de-icing, reducing overall material use
Highly Soluble and Fast Acting: Dissolves quickly, making it effective in brine solutions, ensuring rapid performance in road treatments or industrial processes
Versatile Across Multiple Industries: Applicable in everything from agriculture and manufacturing to environmental management and water systems.
Safety and Handling
Magnesium chloride is generally considered low-hazard, but standard industrial safety practices should still be followed. It may cause mild skin or eye irritation upon contact and can irritate the respiratory tract if dust is inhaled.
