Industrial Grade MgCl2 Magnesium Chloride Hexahydrate Flakes CAS 7791-18-6
Magnesium chloride is a chloride with the chemical formula MgCl2. These colorless crystals are highly deliquescent and represent typical ionic halides that dissolve easily in water. Hydrated magnesium chloride can be extracted from salt water or seawater, typically containing 6 molecules of water of crystallization. At temperatures above 95°C, water of crystallization is lost, and decomposition begins above 135°C, releasing hydrogen chloride (HCl) gas. This compound serves as a raw material for industrial magnesium production and is commonly used in prescription oral magnesium supplements.
- Chemical Industry: Important inorganic raw material for producing magnesium carbonate, magnesium hydroxide, magnesium oxide, and antifreeze.
- Metallurgical Industry: Used to produce metal magnesium (via melt electrolysis), liquid chlorine, and high-purity magnesium sand.
- Building Materials: Essential for manufacturing fiberglass tiles, decorative panels, magnesia cement, fireproof doors, and artificial marble.
- Food Industry: Used as food additives, protein coagulants (produces tender tofu), and flavoring agents.
- Transportation: Effective road deicing agent with lower vehicle corrosion than sodium chloride.
- Medical: Used in "brine dried" medicinal preparations and as a laxative.
- Agriculture: Functions as magnesium fertilizer, potassium magnesium fertilizer, and cotton defoliant.

- Hydrolyzes when heated to produce magnesium oxide and basic magnesium chloride
- Electrolysis in molten state generates magnesium and chlorine gas (MgCl2 → Mg + Cl2↑)
- Forms magnesium hydroxide precipitate in alkaline environments (Mg2+ + 2OH- → Mg(OH)2↓)
