Magnesium chloride is the chemical compound .These salts are typical ionic halides, being highly soluble in water.The hydrated magnesium chloride can be extracted from brine or sea water.
Magnesium chloride hexahydrate (MgCl2·6H2O) is an inorganic salt that can be generated from the acid leach solution of magnesite tailings.It is a potential phase change material (PCM) for storing thermal energy in solar cookers. The result of altering poly (vinyl alcohol)(PVA) films with MgCl2·6H2O has been investigated.
