What Is Aluminum Hydroxide?

Aluminum hydroxide is a white, crystalline compound with the chemical formula Al(OH)₃. As one of the components of aluminum, this substance is typically obtained from natural sources such as bauxite (an aluminum oxide mineral). Aluminum hydroxide is generally used as an intermediate compound in the production of high-purity aluminum. It is also widely used in various applications, such as neutralizing acidic environments and water treatment.

In Which Fields and Products Is It Used?

1. Water Treatment: Aluminum hydroxide is a key compound in water treatment processes. It acts specifically as a coagulant used to purify water. Contaminants and fine particles in the water combine with aluminum hydroxide and settle out. This makes the water cleaner.

2. Antacid (Stomach Medicine): Aluminum hydroxide is a compound used to neutralize stomach acid and is found in many antacid medications. It is used to relieve discomfort caused by stomach acid.

3. Flame Retardant: Aluminum hydroxide is also used as a flame retardant. It is used to produce fire-resistant materials—particularly in plastics, rubber, and textiles—when efforts are made to reduce the risk of fire.

4. Cosmetic Products: In some cosmetic products, aluminum hydroxide is used as an emulsifier or to thicken creams. It is also found in some deodorants and antiperspirants because aluminum compounds have sweat-inhibiting properties.

5. In Water Bottles and Other Coating Products: Aluminum hydroxide can also be used as a protective coating on the surface of aluminum materials. This helps protect aluminum from corrosion, particularly in water bottles, pot lids, and similar products.

6. Cleaning Products: Aluminum hydroxide can be found as a cleaning ingredient in some cleaning products. It is used particularly in sanding and polishing processes.
