- Description:
Product name: Magnesium Chloride
Formula: MgCl.6H2O
CAS NO.: 7786-30-3
EINECS No.:232-094-6
- Characters:
Magnesium chloride is colorless monoclinic crystal, and the industrial product is usually yellowish brown and has a bitter taste. It is easy to absorb moisture and loses 2 molecules of crystal water when it is dissolved in water at 100 °C. The aqueous solution is neutral at room temperature. At 110 ° C, partial hydrogen chloride is lost to decompose, and strong heat is converted to oxychloride, which decomposes at about 118 ° C when heated rapidly. The aqueous solution has an acidic melting point of 118 ° C (decomposed, hexahydrate) and 712 ° C (anhydrous).

- Application:
1.Metallurgical Industry
It is used for the manufacture of refractory materials and the adhesives of the furnace arm, and is the raw material for the production of No. 2 flux and the smelting of metal magnesium.
2.Chemical Industry
Mainly used for the production of various magnesium salts, such as magnesium oxide, magnesium hydroxide, magnesium carbonate, firecrackers solidification agent, also used as a raw material for antifreeze.
3.Building Materials
Made of hard and corrosion-resistant magnesia cement with magnesia (MgO), it can be made into artificial marble, bitter tile, floor, ceiling, decorative board, fire board, greenhouse bracket, inorganic fiberglass greenhouse frame, magnesia heat preservation chicken Houses, Wave Color Tiles, Ventilation Pipes, Partition Boards, Magnesite Covers, Bathtubs, Window Frames, and Mobile Homes.
4.Used as antifreeze in winter construction mechanical industry
In daily life, the use of magnesite can be made into mechanical packing boxes, triangle mats and furniture, etc. It is a good material for “substituting materials by soil”.
5.Food Industry
It is a protein coagulant. The tofu made by using bittern (food-grade magnesium chloride aqueous solution) is much more delicious than tofu made from plaster, and is also used as an additive for some foods.
6.Transportation Industry
It is used as a snow melting agent for roads. It has a fast ice speed and is less corrosive to vehicles. It is more effective than sodium chloride.
7.Medicine Industry
Made of magnesium chloride “halogen” can be used for medicinal purposes.
8.Agriculture
It can be used as magnesium fertilizer, potassium magnesium fertilizer and cotton defoliant.
9.Other
In addition, it can be used as a coal mine fireproofing agent, road dustproof agent, and stable soil.
