Basic Info of Aluminum Hydroxide

What is Aluminum Hydroxide?

Aluminum hydroxide (Aluminiumhydroxide), chemical formula Al(OH)3, white solid, insoluble in water, soluble in acid or alkali, is a typical amphoteric hydroxide. After it is heated and dehydrated in the air, it can be converted into alumina, which is of great significance to the production of alumina.

Aluminum hydroxide can react with acid to form salt and water, and can react with strong base to form salt and water, so it is an amphoteric hydroxide. Because of its certain acidity, it can also be called aluminate (H3AlO3). However, what is actually formed when it reacts with a base is tetrahydroxyaluminate ([Al(OH)4]-). Therefore, it is usually regarded as metaaluminate monohydrate (HAlO2·H2O), which is divided into two types: industrial grade and pharmaceutical grade.

Aluminum hydroxide is a chemical product with a wide range of uses. Industrial grade aluminum hydroxide is mainly used as a filler for plastics and polymers, a flame retardant and a binder for carpet making, a filler for epoxy resin, and a color filler for papermaking. And coatings, production of aluminum sulfate, alum, aluminum fluoride, sodium aluminate, synthetic molecular sieves, production of fillers for toothpaste, ingredients for glass, its gel liquid and dry gel. Pharmaceutical grade aluminum hydroxide is mainly used as an antacid, which has the effect of neutralizing gastric acid and protecting the ulcer surface, and can relieve the symptoms of acid reflux caused by excessive gastric acid. It is suitable for gastric ulcer and duodenal ulcer, reflux disease Treatment of esophagitis and upper gastrointestinal bleeding. When used in combination with calcium and vitamin D, it can treat neonatal hypocalcemia (tetany).

Aluminum Hydroxide Uses

  1. Aluminum hydroxide is widely used in plastic, rubber, resin, paint, paint, etc.
