XRD Chemical is a professional Magnesium Chloride Hexahydrate manufacturer and supplier in China, offering high-purity MgCl₂·6H₂O flakes (46% MgCl₂) for industrial, food, and de-icing applications.
Our magnesium chloride hexahydrate is a colorless, hygroscopic crystalline flake with a molecular weight of 203.31 g/mol. It is the most widely produced and consumed form of magnesium chloride, obtained naturally from seawater, salt lakes, and underground brine deposits. The hexahydrate form contains approximately 53% water of crystallization, giving it excellent solubility in water and making it the preferred choice for liquid brine preparation and direct spreading applications.
Key applications include road de-icing and dust suppression, where it outperforms sodium chloride at lower temperatures, working effectively down to -33°C. In food processing, it is widely used as a coagulant in tofu production (known as Nigari in Japan) and as a mineral supplement. Other uses include magnesium oxide production, fireproofing agents for wood and textiles, binding agents in animal feed, and industrial brine solutions. Food grade (E511), pharmaceutical grade, and Kosher/Halal certified options are available with full documentation.
