What is Mgcl? What is the use?
Magnesium chloride acridine,
Uses: for the production of metal magnesium, disinfectant, frozen brine, ceramics, and used to fill the fabric, paper and so on. The solution is mixed with magnesium oxide, can become hard wear-resistant magnesia cement. Nature: type 95.22. 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, the density of 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. By magnesium oxide or lime soil and hydrochloric acid role in the system. Seawater and salt brine are present in the presence of magnesium chloride.
