Application

Magnesium chloride serves a diverse range of purposes across different industries and applications. As an essential nutrient, magnesium plays a crucial role in various biological functions, such as energy production, protein synthesis, muscle contractility, and nerve excitability. Beyond its biological roles, magnesium chloride is integral in manufacturing processes for textiles, paper, fireproofing agents, cements, and refrigeration brines, and is even involved in dust and erosion control. Mixed with hydrated magnesium oxide, it forms "Sorel-cement," a robust material unmatched by any other compound. Historically, magnesium chloride has been used as an antiseptic, and it shows potential in veterinary medicine for tumor reduction. Environmentally, it aids in controlling dust on unpaved roads while minimizing ecological impact and reducing vehicle maintenance costs. Medically, it is used as a bioavailable magnesium supplement and in various anesthetic applications for marine organisms. In food production, it acts as a coagulant in tofu preparation and is an ingredient in baby formula milk. Additionally, magnesium chloride holds promise as a hydrogen gas storage material, highlighting its versatility and importance across disciplines.
