1. How is high-purity anhydrous magnesium chloride made?


Anhydrous magnesium chloride is a white shiny flake or powder. The preparation method of anhydrous magnesium chloride is different, and the price of the obtained anhydrous magnesium chloride is also different.


At present, the anhydrous magnesium chloride crystallized from high-quality chloride and high-purity metal magnesium under high temperature and vacuum conditions after displacement reaction is in a leading position in the world in terms of technology and quality.


The content of magnesium chloride in the produced anhydrous magnesium chloride can reach 99%, with little or no harmful substances such as sodium chloride and potassium chloride, so it is most suitable for making magnesite products. This type of high-purity anhydrous magnesium chloride has a higher cost.


2. The dosage of high-purity anhydrous magnesium chloride is less than that of halogen tablets


With this kind of anhydrous magnesium chloride with a purity of more than 99%, it is relatively simple to operate anti-halogen, frosting, deformation and other phenomena. The brine produced by hydrolysis is clear and transparent. It can shorten the time of dehydration and coagulation of magnesite products, especially when the temperature is low.


In addition, when the brine is blended, due to its high purity, the magnesium content of the traditional magnesium chloride hexahydrate can be lowered by more than 2-5 degrees. In theory, 1,000 kg of halogen tablets (43% content) = 430 kg of 99% magnesium chloride. 1000 kg of halogen tablets (47% content) = 470 kg of 99% magnesium chloride.


In fact, 1000 kg of 99% magnesium chloride = 2500 kg of halogen flakes (content 43%). 1000 kg of 99% magnesium chloride = 2400 kg of halogen flakes (content 47%).


This kind of high-purity anhydrous magnesium chloride uses less than halogen flakes. Therefore, the cost of production, transportation, loading and unloading and storage can be reduced.


3. Use industrial magnesium chloride hexahydrate to make anhydrous magnesium chloride


There is also a method for preparing anhydrous magnesium chloride from industrial magnesium chloride hexahydrate by repeating the process of heating, concentration and recrystallization. High energy consumption and strict technological process make the price of anhydrous magnesium chloride not low. However, considering its dosage, it is still worthwhile.
