Anhydrous MgCl2 contains 25.5% elemental magnesium by mass. These salts are typical ionic halides, being highly soluble in water. The hydrated magnesium chloride can be extracted from brine or sea water. In North America, magnesium chloride is produced primarily from Great Salt Lake brine. It is extracted in a similar process from the Dead Sea in the Jordan Valley. Magnesium chloride, as the natural mineral bischofite, is also extracted (by solution mining) out of ancient seabeds, for example, the Zechstein seabed in northwest Europe. Some magnesium chloride is made from solar evaporation of seawater. Anhydrous magnesium chloride is the principal precursor to magnesium metal, which is produced on a large scale. Hydrated magnesium chloride is the form most readily available.<\/p>\n","protected":false},"featured_media":12480,"template":"","meta":[],"product_brand":[],"product_cat":[321,40,62,64],"product_tag":[],"class_list":{"0":"post-12472","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-fertilizers","7":"product_cat-uncategorized","8":"product_cat-household-chemicals","9":"product_cat-pharmaceuticals","11":"first","12":"instock","13":"taxable","14":"shipping-taxable","15":"purchasable","16":"product-type-variable","17":"has-default-attributes"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.2 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Magnesium chloride (CAS 7791-18-6) - Chemistry For Industry - Solvents &amp; Chemicals - Masterchem.ee<\/title>\n<meta name=\"description\" content=\"Magnesium chloride is the name for the chemical compound with the formula MgCl2 and its various hydrates MgCl2(H2O)x.
