Anhydrous Magnesium Chloride
- Anhydrous Magnesium Chloride is a crystalline solid chemical compound. The crystal structure of MgCl2 is layer-like. It is very hygroscopic and highly soluble in water and alcohol. It can be prepared by heating hydrated magnesium chloride crystals in a current of dry hydrogen chloride or by heating magnesium ammonium chloride. Anhydrous magnesium chloride contains 25.5% elemental magnesium by mass. It is the principal precursor to magnesium metal, which is produced on a large scale. Magnesium chloride anhydrous is supplied in flake and powder forms.
- Weifang Bell Chemical is a top Anhydrous Magnesium Chloride Manufacturer and direct factory exporter in China.

Anhydrous Magnesium Chloride Vs. Hexahydrate Magnesium Chloride
Magnesium chloride is a summary name of anhydrous magnesium chloride and its various hydrates.
Anhydrous magnesium chloride contains an assay of more than 98% and has no crystal water. It contains approximately 25.5% magnesium by mass. Anhydrous magnesium chloride is the primary material for the production of magnesium metal.The content of hexahydrate magnesium chloride is around 46%. Hexahydrate magnesium chloride is the hexahydrate form of magnesium chloride. It can be extracted from brine or seawater.
The two materials can be distinguished by their appearance. Anhydrous magnesium chloride only has white color, While hexahydrate magnesium chloride has yellow and white colors according to the concentration. They all have flake form. However, anhydrous magnesium chloride flake is thinner than hexahydrate. Anhydrous magnesium chloride looks drier.
Anhydrous magnesium chloride is much more expensive than hexahydrate. It attracts moisture faster in the atmosphere.It can be prepared by heating hydrated magnesium chloride crystals in a current of dry hydrogen chloride.
