What is the crystal structure of MgCl2
Chemical Name: Magnesium Chloride [1] (MgCl2) Chemical Description: English name is magnesiumchloride. The chemical formula MgCl2 is composed of 74.54% chlorine and 25.48% magnesium, with a relative molecular mass of 95.21. Was colorless hexagonal crystals. Density 2.316-2.33 g / cm 3. Melting point 714 ° C. The boiling point of 1412 ℃. Usually contains six molecules of crystal water, that is, MgCl2 · 6H2O, easy deliquescence. For the monoclinic crystal, with or salty, there is a certain corrosive. Its density 1.569 g / cm 3, the melting point of 116-118 ° C, while decomposition. Soluble in water, heating and dehydration and hydrogen chloride from magnesium oxide. Use [2]: for the production of metal magnesium, disinfectant, frozen brine, ceramics, and used to fill the fabric, paper and so on. The solution and magnesium oxide mixed, can become hard wear-resistant magnesia cement. Method: from magnesium oxide or lime soil and hydrochloric acid role in the system. Seawater and salt brine are present in the presence of magnesium chloride. The shape of magnesium chloride [3]: generally in flake, block, crystal, particles and powder-based. Content of about 46% of magnesium chloride hexahydrate, 99% of anhydrous magnesium chloride. Magnesium chloride Chemical and physical properties: soluble in water and ethanol. Sensory indicators: white crystals, columnar or needle-like, bitter taste.
