Product Application of Magnesium chloride CAS#7786-30-3
Magnesium chloride serves diverse uses beyond magnesium metal production. It is applied in textiles, paper manufacturing, fire retardants, cement materials, and refrigeration brines. It also supports dust control and erosion prevention. When blended with hydrated magnesium oxide, magnesium chloride forms a hard substance known as Sorel‑cement. This cement consists of MgO (caustic calcined magnesia) and MgCl₂, with an approximate formula Mg₄Cl₂(OH)₆(H₂O)₈, corresponding to a mass ratio of 2.5–3.5 parts MgO to 1 part MgCl₂. This application of magnesium chloride is unique and not matched by other compounds. Magnesium chloride was among early antiseptics, first utilized by Dr Pierre Delbert in 1915. A 1989 veterinary study suggested potential anti‑tumor activity when used as a feed additive.
