Anhydrous Magnesium Chloride : As refractory and smelting magnesite metal material in metallurgy industry. In building industry, it can make artificial stone mixtured with caustic magnesite into cement.
Magnesium Chloride Hexahydrate: The formula is MgCl2·6H2O ,White flake,White Pellet,White Powder.
Magnesium chloride granules or flakes as industrial grade usually contains six molecules of crystal water, namely MgCl2 · 6 h2o, easy deliquescence, put in dry air will lose crystal water of weathering.
As the monoclinic crystal, salty, has certain corrosion resistance. For making metal magnesium, disinfectants, frozen brine, pottery and porcelain, and used to fill the fabric, paper, etc. Its solution is mixed with magnesium oxide, also can become hard and wear resistance of magnesia cement.
Applications of Magnesium Chloride :
Magnesium chloride is used for low-temperature de-icing of highways, sidewalks, and parking lots. When highways are treacherous due to icy conditions, magnesium chloride helps to prevent the ice bond, allowing snow plows to clear the roads more efficiently.
Magnesium chloride is used in three ways for pavement ice control: Anti-icing, when maintenance professionals spread it onto roads before a snow storm to prevent snow from sticking and ice from forming; pre-wetting, which means a liquid formulation of magnesium chloride is sprayed directly onto salt as it is being spread onto roadway pavement, wetting the salt so that it sticks to the road; and pre-treating, when magnesium chloride and salt are mixed together before they are loaded onto trucks and spread onto paved roads.
Magnesium chloride has shown promise as a storage material for hydrogen. Ammonia, which is rich in hydrogen atoms, is used as an intermediate storage material. Ammonia can be effectively absorbed onto solid magnesium chloride, forming Mg(NH3)6Cl2. Ammonia is released by mild heat, and is then passed through a catalyst to give hydrogen gas.
Mixed with hydrated magnesium oxide, magnesium chloride forms a hard material called Sorel cement.
Building Industry
Magnesium chloride as the main raw materials in building materials industry. such as glass fiber tiles, decorative materials, sanitary ware, ceiling, floor brick, magnesia cement, ventilation pipes, anti-theft covers, fireproof doors and Windows, fire prevention board, partition board, the production of artificial marble and so on high-rise building equipment important raw materials.
Because magnesium is a mobile nutrient, magnesium chloride can be effectively used as a substitute for magnesium sulfate (Epsom salt) to help correct magnesium deficiency in plants via foliar feeding. It is advisable to use a smaller dose when using magnesium chloride compared to the recommended dose of magnesium sulfate (20 g/L). This is due primarily to the chlorine present in magnesium chloride, which can easily reach toxic levels if over-applied and/or applied too often.
It has been found that higher concentrations of magnesium in tomato and some pepper plants can make them more susceptible to disease caused by infection of the bacteria Xanthomonas campestris, since Mg is essential for bacterial growth.
Magnesium chloride is a type of neutraceutical preparation of magnesium as nutritional supplement. For fertilizer industry, as mineral supplement for animals .
Culinary Usage
Magnesium chloride (E511) is an important coagulant used in the preparation of tofu from soy milk. In Japan it is sold as nigari , derived from the Japanese word for "bitter"), a white powder produced from seawater after the sodium chloride has been removed, and the water evaporated. In China, it is called lushui . Nigari or lushui consists mostly of magnesium chloride, with some magnesium sulfate and other trace elements. It is also an ingredient in baby formula milk.
Additive for marine aquariums,aquaculture,shrimp pond,fireproof wood, dust proofing, wastewater treatment, artificial seawater,manufacture of textiles, steel industry and magnesium metal electrolysis.etc.
