Use
Aluminum hydroxide, white solid, is a typical amphoteric hydroxide that is insoluble in water but soluble in acid or alkali. It can be transformed into alumina after heated in the air for dehydration, which is important for alumina production. Aluminum hydroxide is a widely used chemical product, and it is mainly used as plastic and polymer fillers, blanket flame retardant and binder, epoxy resin filler, toothpaste fillers, glass ingredients as well as paper color fillers and coatings. It can be also used to product sulfuric acid Aluminum, alum, aluminum fluoride and sodium aluminate, and to synthesize molecular sieve. The gel and drying gel of aluminum hydroxide can be used in medicine as antacids to neutralize gastric acid and protect ulcer surface for the treatment of gastric and duodenal ulcer disease and hyperacidity.
