Nature：
Magnesium chloride English name: Magnesium Chloride Chemical formula: MgCl2·6H2O. Light yellow, white flake, granular, density 2.316-2.33 g/cm3, melting point 714℃, boiling point 1412℃. Usually contains six molecules of crystal water, namely MgCl2·6H2O, which is easy to deliquesce. It is a monoclinic crystal, has a salty taste and is corrosive to a certain extent. Its density is 1.569 g/cm3 and its melting point is 116-118°C.
Use：
1. Metallurgical industry: Adhesives used to make refractory materials and furnace arms, and are raw materials for making No. 2 flux and smelting magnesium metal.
2. Chemical industry: mainly used to make various magnesium salts, such as magnesium oxide, magnesium hydroxide, and magnesium carbonate.
3. Building materials: In the construction industry, it is a raw material for the production of magnesium cement and is used as an antifreeze during winter construction. Made of hard corrosion-resistant magnesia cement with magnesite (MgO), which can be made into artificial marble, magnesite tiles, floors, ceilings, decorative boards, fireproof boards, greenhouse brackets, partition boards, magnesite manhole covers, bathtubs , door and window frames and mobile homes, etc. ​
4. Machinery industry: In daily life, cypress soil can be used to make mechanical packaging boxes, triangular pads and furniture, etc. It is a good material for "replacing materials with soil". ​
5. Transportation industry: Used as a road ice and snow melting agent. It melts ice quickly and is less corrosive to vehicles. It is more effective than sodium chloride. ​
6. Medicine: Magnesium chloride is used to make "halogen" for medicinal purposes.
7. Agriculture: It can be used as magnesium fertilizer, potash-magnesium fertilizer and cotton defoliant.
8. Use high-quality magnesium chloride as environmentally friendly hardener
9. Use as a fixing agent (solidifying agent) for firecrackers
10. Adding magnesium chloride powder to rubber powder can increase its hardness
11. Food grade magnesium chloride can be used as a stabilizer or coagulant in soy products.
12. Other fields (in addition, it can also be used as coal mine fire retardant, highway dust control agent, and soil stabilization)
