Message InquiryProduct Description
Magnesium chloride, calculated based on the weight of the anhydrous substance, consists of 74.54% chlorine and 25.48% magnesium. However, according to the phase diagram analysis of the MgCl2-H2O system, in addition toanhydrous substance, there are also hydrates containing 1, 2, 4, 6, 8, and 12 crystallization waters. When dehydrated in the air, it can only release about 4 molecules of water, which does not cause serious side reactions.
Anhydrous magnesium chloride is a white, glossy hexagonal crystal with a melting point of 714°C and a boiling point of 1412°C.Hygroscopicityis extremely strong, higher than that of hexahydrate and dihydrate magnesium chloride. The physical and chemical properties are basically the same as those of hexahydrate magnesium chloride. It is mainly used for the production of metallic magnesium and in the chemical, light industry, coal, construction, and other sectors.
1. In the chemical industry, it is an important inorganic raw material used to produce magnesium carbonate,magnesium hydroxide,magnesium oxideand other magnesium products, and is also used asa raw material for antifreeze.的原料等。
2. In the metallurgical industry, it is used to produce metallic magnesium (obtained through molten electrolysis), liquid chlorine, and high-purity magnesium sand.
3. In the building materials industry, it is used to produce lightweight building materials such as fiberglass tiles, decorative panels, sanitary ware, ceilings, floor tiles, magnesium oxide cement,ventilation ducts, anti-theft manhole covers, fire doors and windows, fireproof boards, partition boards, and is an important raw material for producingartificial marble.In magnesium products, it can be used to make high-quality magnesium tiles, high-quality fireproof boards, magnesium packaging boxes, magnesium decorative boards, lightweight wall panels, grinding tools, furnace tools, and fireworks solid propellant.
4. In other fields, it can be used asfood additives, protein coagulants,de-icing agents, refrigerants, dust suppressants, refractory materials, etc. Tofu made with brine (magnesium chloride solution) is more tender and flavorful than tofu made with gypsum.
5. In the metallurgy industry: used to manufacture refractory materials and binders for furnace arms, and is a raw material for producing second-grade flux and smelting metallic magnesium.
6. In the machinery industry: in daily life, magnesium sulfate can be used to make mechanical packaging boxes, triangular pads, and furniture, making it a good material for "using soil instead of materials."
7. In the transportation industry: used as a road de-icing agent, it melts ice quickly and has low corrosiveness to vehicles, outperforming sodium chloride.
8. Medicine: magnesium chloride can be made into "brine" for medicinal use. It can be used as a laxative.
9. Agriculture: can be used to produce magnesium fertilizers, potassium-magnesium fertilizers, and cotton defoliants.
10. Curing agents; nutritional enhancers; flavoring agents (used in combination with magnesium sulfate, table salt, calcium hydrogen phosphate, calcium sulfate, etc.);Japanese sakeand other fermentation aids; dehydrating agents (used in fish cakes, dosage 0.05% to 0.1%); texture improvers (used in combination with polyphosphates as elasticity enhancers for surimi products). Due to its strong bitterness, it is often used in amounts less than 0.1%.
