White Flakes 46% Magnesium Chloride Hexahydrate Factory

1. Physical and Chemical Parameters

1.1 Physical Parameters

Bulk density of flakes: 0.8~1.0 g/cm³ Melting point (with crystal water): 116~118 ℃ Boiling point (decomposition temperature): 1412 ℃ Solubility: Easily soluble in water (solubility 54.3 g/100g water at 20 ℃); soluble in polar solvents such as ethanol and acetone; heat is released during dissolution. Hygroscopy: Strongly hygroscopic and prone to deliquescence; sealed storage is required.

1.2 Chemical Parameters

pH value of aqueous solution: pH 5.5~7.0 for 10% aqueous solution, weakly acidic to neutral CAS No. of magnesium chloride hexahydrate: 7791-18-6 Molecular formula: MgCl₂·6H₂O; molar mass: 203.3 g/mol Chemical properties: Reacts with alkalis to form magnesium hydroxide precipitate; reacts with carbonates to form magnesium carbonate precipitate; decomposes into magnesium oxide and hydrogen chloride gas at high temperature.

2. Basic Composition & Specification Parameters

46% magnesium chloride flakes refer to flake-shaped magnesium chloride products with effective magnesium chloride (calculated as anhydrous MgCl₂) content ≥ 46%. It is a commonly used form of magnesium chloride in industrial applications, manufactured by professional magnesium chloride factories. The core basic parameters are listed below:

 3. Differences Between White Magnesium Chloride Flakes and Ordinary Magnesium Chloride Flakes

1. Content: Ordinary magnesium chloride flakes have a content of around 46%, while white magnesium chloride flakes reach approximately 47% with labeled specification of 46%-46.5%.

2. COA indicators: Differences in heavy metals, insoluble matter and other impurity indicators.

3. Clarity of aqueous solution after dissolution.

4. Color: The 46% white magnesium chloride flakes are milky white; higher-grade white flakes are transparent. Ordinary magnesium chloride flakes are mostly grayish-white or brown.
