1. Basic Product Information
Product Introduction: Anhydrous magnesium chloride is a high-end basic inorganic magnesium salt raw material, refined by high-temperature dehydration and purification process. It is manufactured in accordance with GB/T 26521-2011 and GB 25584-2010 national standards, divided into three grades: Class I high-purity premium grade, Class II general industrial grade, and food grade. Featuring high purity, ultra-low impurities, excellent solubility and superior thermal stability, the product has strong aqueous conductivity and stable chemical activity. It is widely used in metallurgy, magnesium oxide building materials, environmental water treatment, chemical synthesis, food processing, agricultural breeding, and petrochemical industries. It is an essential core raw material for magnesium salt production, metal magnesium smelting and magnesium oxychloride building materials manufacturing.
2. Physical and Chemical Properties
The product is a white, odorless, transparent crystal or powder with a bitter-salty taste. It exhibits strong hygroscopicity at room temperature and deliquesces rapidly when exposed to air. It is extremely soluble in water with a fast dissolution speed and exothermic dissolution. The aqueous solution is clear, weakly acidic, and highly conductive. It is soluble in ethanol and acetone but insoluble in most hydrocarbon solvents. It possesses excellent thermal stability with a melting point of 714℃ and a boiling point of 1412℃, maintaining stable performance without decomposition under high-temperature working conditions. With mild and low-corrosive chemical properties, it causes minimal equipment loss. Stably stored in sealed and dry environments, it ensures consistent batch quality and adapts to automated continuous production lines with strong industrial versatility and compatibility.
