Mg 2 Cl -1
Production and Reactions
According to the Dow method, seawater is the source of magnesium. After the sea water is treated with lime, magnesium hydroxide is obtained. Magnesium chloride is obtained from the reaction of magnesium hydroxide with chloride acid. Pure magnesium chloride (MgCl 2) can be obtained by electrolysis. It can be extracted from salt water or sea water.
It is used in drilling and grinding wheels in cement sector.
It is used in chemical production and dust binding in this sector.
Magnesium chloride is produced as magnesium oil with water mixture and applied on the skin.
It is effective in solving indigestion and constipation problems in medicine.
Production of magnesium metal is used in this sector.
It is used in ex-proof and fireproofing agents, as an additive in textile and paper production, in disinfectants, fire extinguishers and ceramics.
