Overview

XRD Chemical is a professional Magnesium Chloride Anhydrous manufacturer and supplier in China, offering high-purity anhydrous MgCl₂ powder (99%) for specialized industrial and chemical applications.

Our magnesium chloride anhydrous is a white, highly hygroscopic crystalline powder with a molecular weight of 95.21 g/mol. Unlike the more common hexahydrate form, the anhydrous grade contains no water of crystallization, making it essential for applications where moisture would interfere with chemical reactions or product quality. The powder exhibits a hexagonal crystal structure of the CdCl₂ type, consisting of cubic close-packed chloride ions with magnesium ions occupying all octahedral interstices.

Key applications include magnesium metal production via electrolysis of molten MgCl₂, a primary industrial route to lightweight structural metal. It also serves as a Lewis acid catalyst in organic synthesis, a precursor for Grignard reagent preparation, a raw material for magnesium oxychloride (Sorel) cement and fireproofing compositions, and a laboratory reagent for competent cell preparation. Pharmaceutical grade is available for use as a magnesium source in parenteral nutrition and dialysis solutions.

FAQ

Q What is Magnesium Chloride Anhydrous?

Magnesium Chloride Anhydrous (MgCl₂) is a white, highly hygroscopic crystalline powder with 99% purity. Unlike the hexahydrate form which contains crystal water, the anhydrous form contains no water of crystallization. It has a molecular weight of 95.21 g/mol and adopts a hexagonal crystal structure of the CdCl₂ type.

Q What is the difference between anhydrous and hexahydrate magnesium chloride?

Anhydrous magnesium chloride (MgCl₂) contains no crystal water and has 99% purity, making it suitable for moisture-sensitive applications like magnesium metal production and chemical synthesis. Hexahydrate magnesium chloride (MgCl₂·6H₂O) contains approximately 53% water of crystallization and is primarily used for de-icing, dust control, and food processing. The anhydrous form is more expensive but essential where water content must be minimized.

Q What are the primary applications of anhydrous magnesium chloride?

Anhydrous magnesium chloride is primarily used as feedstock for magnesium metal production via molten salt electrolysis. It also serves as a Lewis acid catalyst in organic synthesis, a precursor for Grignard reagents, a raw material for magnesium oxychloride (Sorel) cement, a fireproofing agent, a laboratory reagent for competent cell preparation, and a pharmaceutical-grade magnesium source in parenteral nutrition solutions.

Q How should anhydrous magnesium chloride be stored?

Store in tightly sealed containers in a cool, dry place at room temperature (15-25°C is optimal). The product is highly hygroscopic and will rapidly absorb moisture from the air if left exposed, potentially forming hexahydrate. Keep away from water and humidity. Under proper storage conditions in sealed containers, shelf life is up to 5 years.

Q Is anhydrous magnesium chloride available in food or pharmaceutical grade?

Yes, XRD Chemical supplies pharmaceutical-grade anhydrous magnesium chloride that meets USP/BP/EP standards. This grade is used as a magnesium source in parenteral nutrition solutions, dialysis fluids, and pharmaceutical preparations. Food-grade magnesium chloride (E511) is typically supplied in the hexahydrate form for tofu coagulation and mineral supplementation. Contact us for specific grade requirements and documentation.
