Description
High-Purity Crystalline Aluminum Chloride (AlCl₃·6H₂O)
Product Description
Crystalline Aluminum Chloride, also known as Crystalline AlCl₃ or Aluminum Chloride Hexahydrate, is a white or slightly yellow crystal with a mild hydrochloric acid odor. It is widely used in water treatment, precision casting, papermaking, pharmaceuticals, and cosmetics. Our product is refined to produce high-purity white crystals.
Applications
- Water Treatment
- Ideal for drinking water purification, especially effective for cold, low-turbidity, and slightly alkaline water.
-
- Precision Casting (Hardeners)
- Acts as a superior hardening agent compared to magnesium chloride and ammonium chloride.
- Offers higher shell strength and about 3% higher product yield.
- Requires lower dosage and offers reduced overall cost.
- No harmful gas emissions during use, improving workplace conditions.
-
- Other Industries
- Also used in pharmaceuticals, personal care, and cosmetics manufacturing.

Technical Specifications
| Item | Premium Grade | First Grade |
| Appearance | White crystals | White crystals |
| AlCl₃·6H₂O Content (%) | ≥ 97.5 | ≥ 95.5 |
| Fe Content (%) | ≤ 0.002 | ≤ 0.01 |
| Insoluble in Water (%) | ≤ 0.025 | ≤ 0.1 |
Usage Instructions
- Water Treatment
- Dilute the product 5–20 times with water. Stir to fully dissolve and dose appropriately based on water quality.
-
- Precision Casting
- For new hardener preparation, mix 50 kg of aluminum chloride with 100 kg of water to form a 33% concentration solution.
- During usage, AlCl₃ content will gradually decrease, while pH and viscosity will increase.
- Adjust by adding more aluminum chloride to maintain the proper concentration.
- If pH exceeds 1.7, add a small amount of industrial hydrochloric acid.
-
