Frequently Asked Questions
What are the main types of Magnesium Chloride you offer?
We supply two main specifications: Magnesium Chloride Anhydrous (with a purity level of 99% min in powder or flake form) and Magnesium Chloride Hexahydrate (with a purity level of 99% min and 46% active MgCl2, available in flake, granular, or pellet form).
What is the difference between Anhydrous and Hexahydrate Magnesium Chloride?
The main differences lie in their chemical formula and form. Magnesium Chloride Anhydrous (MgCl2) contains no water crystallization and has a higher active concentration (~99% min), while Magnesium Chloride Hexahydrate (MgCl2·6H2O) contains six water molecules, resulting in an active magnesium chloride concentration of about 46%.
How is Magnesium Chloride utilized in the construction industry?
It is primarily combined with magnesium oxide (MGO) to produce durable, corrosion-resistant magnesia cement. This cement is widely used to manufacture artificial marble, flooring, ceilings, partition boards, fireproof boards, and bathtubs.
Can Magnesium Chloride be used in food processing?
Yes, Magnesium Chloride serves as a food additive and is famously used as a coagulant in making bean curd (tofu), making the tofu more tender and delicious.
What are the chemical CAS registry numbers for these products?
The CAS Registry Number for Magnesium Chloride Anhydrous is 7786-30-3, and the CAS Registry Number for Magnesium Chloride Hexahydrate is 7791-18-6.
What are the main metallurgy applications of Magnesium Chloride?
In metallurgy, it is essential for manufacturing refractory materials, acting as a raw material for producing number 2 flux, and facilitating the smelting process of metallic magnesium.
