Aluminum Hydroxide with CAS 21645-51-2

What is Aluminum Hydroxide?

Aluminum hydroxide, a white solid, is insoluble in water but soluble in acids and alkalis, making it a typical amphoteric hydroxide. Upon dehydration by heating in air, it can be converted into aluminum oxide, which is of great significance in alumina production. Aluminum hydroxide reacts with both acids to form salt and water, and with strong bases to form salt and water, making it an amphoteric hydroxide. Because it exhibits a certain degree of acidity, it is also called aluminic acid.

Specification

Application

Aluminum hydroxide is a widely used chemical product. Industrial-grade aluminum hydroxide is primarily used as a filler in plastics and polymers, a flame retardant and binder in carpets, a filler in epoxy resins, a colorant and coating in papermaking, and in the production of aluminum sulfate, alum, aluminum fluoride, and sodium aluminate; synthesized molecular sieves; a filler in toothpaste; and as a glass ingredient.

Pharmaceutical-grade aluminum hydroxide is primarily used as an antacid, neutralizing gastric acid and protecting ulcer surfaces. It can alleviate symptoms such as acid reflux associated with excessive gastric acid and is suitable for the treatment of gastric and duodenal ulcers, reflux esophagitis, and upper gastrointestinal bleeding. When used in combination with calcium supplements and vitamin D, it can treat neonatal hypocalcemia (tetany).

Features

1. The product is stable and can be mass-produced. Raw materials are abundant, the product is high in purity, and it is easily soluble in acids and alkalis.
2. It provides filling, flame retardancy, and smoke suppression functions, and is non-toxic and harmless.
3. It exhibits high thermochemical stability, thermal strength, creep resistance, dielectric properties, and a low coefficient of thermal expansion.
