white magnesium chloride

White magnesium chloride generally refers to white flake magnesium chloride, a type of magnesium chloride hexahydrate with relatively thin flakes, also known as high-purity magnesium chloride hexahydrate. Its chemical formula is MgCl2.6H2O, with a molecular weight of 203.31 and CAS No.: 7786-30-3. It differs from conventional industrial brine flakes produced by traditional processes.

I. Characteristics of white magnesium chloride hexahydrate

Appearance: Transparent white or translucent white.

High Purity: manufacturers of magnesium chloride hexahydrate usually mark a content of 46% on product packages, while the actual content is higher than 46%.

Low Impurity Content: This white magnesium chloride is produced via pure chemical synthesis. A simple water solubility test (mix white magnesium chloride with purified water at a ratio of 1:1 and observe the solution after around 20 minutes) shows far fewer suspended flocs and sediments. Its aqueous solution is much clearer and nearly colorless compared with that of regular brine flakes and conventionally produced magnesium chloride hexahydrate.

Good Anti-Caking Property: With 13 years of experience in this industry, our team has continuously conducted experiments and optimizations. Under the same storage conditions, our products can significantly delay caking. Magnesium chloride hexahydrate is inherently hygroscopic. When kept in well-sealed packaging, its shelf life can reach up to 2 years.

Applicable for Special Industries: Thanks to its superior performance, it meets the strict requirements of specialized industries for indicators such as sulfate ions, calcium ions, sodium ions and heavy metals.

III. Production Process of White Flake Magnesium Chloride

Our white flake magnesium chloride hexahydrate is manufactured through proprietary chemical synthesis and is one of our core products. This process is different from the conventional precipitation and bleaching methods. Although priced 10%–15% higher than regular magnesium chloride hexahydrate, it delivers more stable performance. Classified as industrial grade, its technical parameters are close to those of food-grade magnesium chloride hexahydrate.

IV. how to select white flake magnesium chloride

Despite its outstanding advantages, you shall select products based on your actual usage demands first. Most buyers have clear technical indicators, such as the maximum allowable content of sulfate ions and sodium ions.

In addition, take product price and transportation conditions into consideration. Long sea transportation often leads to moisture absorption and caking of magnesium chloride hexahydrate upon arrival at factories.

It is worth noting that white magnesium chloride is unnecessary for some industries such as the coal mining industry.
