Building Materials Magnesium Chloride Chemical MgCl2 Anhydrous 7786-30-3

Magnesium chloride (MgCl2) is a colorless, easily deliquescent crystal compound that readily dissolves in water. The hydrated form can be extracted from brine or seawater, typically containing 6 molecules of crystal water. When heated to 95°C, it loses crystal water and begins decomposing above 135°C, releasing hydrogen chloride (HCl) gas.

• Metallurgical Industry: Used as an adhesive for refractory materials and furnace arms, and as raw material for No. 2 flux and magnesium metal smelting.
• Chemical Industry: Primary material for producing various magnesium salts (magnesium oxide, hydroxide, carbonate), firecracker fixatives, and antifreeze components.
• Building Materials: Forms hard, corrosion-resistant magnesia cement when combined with magnesia clay (MgO), used in construction elements including artificial marble, fireproof boards, greenhouse frameworks, and winter construction antifreeze.
• Mechanical Industry: Used in manufacturing mechanical packaging, furniture components, and as a sustainable material alternative.
