Magnesium chloride (MgCl₂) is an inorganic ionic ceramic compound that exists primarily as a hydrated salt in industrial applications, though anhydrous forms are used in specialized contexts. It serves as a raw material and processing agent across chemical, construction, and de-icing industries, valued for its hygroscopic properties and ability to form stable complexes. Engineers select MgCl₂ for applications requiring chloride sources, magnesium ion release, or its capacity to modify material properties—such as dust suppression on unpaved roads, cement additives for magnesium oxychloride cements, and as an electrolyte precursor in magnesium extraction and battery technologies.
