High-Purity Magnesium Chloride (MgCl₂) – Multi-Industry Grade for De-Icing, Agriculture, Construction & Chemical Applications

Magnesium Chloride (MgCl₂) is a highly soluble inorganic salt widely used across industrial, agricultural, environmental, and construction sectors. Available in flake, pellet, powder, or liquid brine form, Magnesium Chloride is valued for its hygroscopic nature, high solubility, and efficient performance in moisture control, dust suppression, de-icing, and chemical processing applications.

Magnesium Chloride is typically produced from natural brine sources or through chemical synthesis, resulting in a white to off-white crystalline solid. It readily dissolves in water, forming a clear solution that remains effective even at low temperatures. Its ability to attract and retain moisture makes it highly effective in environmental and infrastructure applications.

In the de-icing and road maintenance industry, Magnesium Chloride is widely used for snow and ice control. It lowers the freezing point of water, allowing for effective ice melting at lower temperatures compared to traditional rock salt. It also generates heat when dissolving, enhancing its de-icing efficiency. Additionally, it is less corrosive than sodium chloride when properly applied, making it suitable for highways, bridges, and airport runways.

In the agricultural sector, Magnesium Chloride serves as a magnesium source for crops and soil conditioning. Magnesium is a vital nutrient required for chlorophyll production and enzyme activation. When applied appropriately, it helps improve plant growth, nutrient uptake, and overall crop health.

Within the construction industry, Magnesium Chloride is used in the production of magnesium oxychloride cement (Sorel cement), which is known for its high strength, fire resistance, and rapid setting characteristics. It is also applied for dust control on unpaved roads, construction sites, and mining operations due to its moisture-retaining properties.

In industrial and chemical processing, Magnesium Chloride functions as a raw material in the production of magnesium metal, textiles, paper, and various magnesium compounds. It is also utilized in wastewater treatment and as a coagulating agent in tofu production (food-grade specification).

Typical Technical Specifications:

• Chemical Formula: MgCl₂
• Appearance: White flakes, pellets, or clear liquid (brine)
• Purity: 94–98% (flake/pellet grade)
• Magnesium Chloride Content: ≥ 46% MgCl₂ (anhydrous basis varies)
• Solubility: Highly soluble in water
• pH (5% solution): Slightly acidic to neutral
• Hygroscopic: Yes

Key Benefits of Magnesium Chloride:

• Effective de-icing performance at low temperatures
• Excellent moisture absorption and dust control properties
• Essential magnesium source for agriculture
• Supports production of specialty cements
• Highly soluble and easy to apply
• Available in multiple grades and forms

Magnesium Chloride should be stored in sealed packaging in a dry, ventilated area to prevent clumping due to moisture absorption. Liquid brine solutions should be stored in corrosion-resistant tanks.

With its versatility, efficiency, and wide-ranging applications, Magnesium Chloride remains a critical material in infrastructure maintenance, agriculture, industrial manufacturing, and environmental management worldwide.
