Magnesium Chloride
MgCl2
Magnesium salt used in de-icing, dust control, magnesia cement and as an industrial magnesium source.
- Chemical name
- Magnesium chloride
- CAS number
- 7786-30-3
Product overview
Magnesium chloride is a water-soluble magnesium salt, commonly traded in flake or crystalline hydrate forms. It is hygroscopic and effective at lowering the freezing point of water.
Applications include road de-icing and dust control, magnesium oxychloride (Sorel) cement and boards, and use as a magnesium source in chemical processing. It is also used as a coagulant in food production where a food-grade material is specified.
