Magnesium chloride is an inorganic substance with a molecular weight of 95.211. It is a colorless flaky crystal, slightly soluble in acetone, soluble in water, ethanol, methanol, and pyridine. It deliquesces and smokes in moist air, and sublimates when it is white hot in a hydrogen gas stream. Magnesium chloride is mainly distributed in the salt lake of Qaidam in China.

Application areas:

1.It is an important inorganic raw material in the chemical industry and is used to produce magnesium products such as magnesium carbonate, magnesium hydroxide, magnesium oxide, and is also used as a raw material for antifreeze.

2.Used in the metallurgical industry to produce magnesium metal(Made by molten electrolysis)、Liquid chlorine and high-purity magnesia, etc.

3.In the building materials industry, it is an important raw material for producing light building materials such as fiberglass tiles, decorative panels, sanitary ware, ceilings, floor tiles, magnesia cement, ventilation ducts, anti-theft manhole covers, fireproof doors and windows, fireproof panels, partition boards, and the production of artificial marble and other high-rise building supplies. Magnesium products can be made into high-quality magnesium tiles, high-quality fireproof panels, magnesium packaging boxes, magnesium decorative panels, lightweight wall panels, molds, stoves, fireworks solidifiers, etc.

4.In other fields, it can be used as food additives, protein coagulants, snow melting agents, refrigerants, dust suppressants, refractory materials, etc. Tofu made with brine (magnesium chloride aqueous solution) is more tender and delicious than tofu made with gypsum.

5.Metallurgical industry: used to make refractory materials and adhesives for building furnace arms, and is the raw material for making No. 2 flux and smelting magnesium metal.

6.Mechanical industry: In daily life, magnesia can be used to make mechanical packaging boxes, triangular pads and furniture, etc. It is a good material for "substituting soil for materials".

7.Transportation industry: Used as a road de-icing and snow-melting agent, it has a fast de-icing speed and is less corrosive to vehicles, which is more effective than sodium chloride.

8.Medicine: Magnesium chloride can be used as medicine to make "dried brine". It can be used as a laxative.

9.Agriculture: It can be used to make magnesium fertilizer, potassium magnesium fertilizer and cotton defoliant.

10.Solidifying agent; Nutritional enhancer; Flavoring agent(Used in combination with magnesium sulfate, salt, calcium hydrogen phosphate, calcium sulfate, etc.)；Fermentation aid for Japanese sake, etc.; dehumidifier(For fish cake, dosage 0.05%～0.1%)；Texturizing Agents(Used in combination with polyphosphates as an elasticity enhancer for surimi products)。Due to its strong bitter taste, the commonly used dosage is less than 0.1%.
