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.

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.
-
