Alumina Trihydrate - ATH

Annual production of Alumina Trihydrate is around 100 million tons which is nearly all produced through the Bayer process. The Bayer process dissolves bauxite (Aluminium Ore) in sodium hydroxide at elevated temperatures. Alumina Trihydrate is then separated from the solids that remain after the heating process. The solids remaining after the Alumina Trihydrate is removed is highly toxic and presents environmental issues.

Applications

Over 90% of all Alumina Trihydrate produced is converted to Aluminium Oxide (alumina) that is used to manufacture aluminum. As a flame retardant, Alumina Trihydrate is chemically added to a polymer molecule or blended in with a polymer to suppress and reduce the spreading of a flame through a plastic. Alumina Trihydrate is also used as an antacid that can be ingested in order to buffer the pH within the stomach.

Description

Alumina Trihydrate has a number of common names used throughout the chemical industry which include: Hydrate Alumina, Alumina Hydrate, Aluminium Tri Hydroxide, ATH, Aluminium Hydrate and Aluminium Hydroxide. Alumina Trihydrate is a white, odorless, powdery, solid substance. Alumina Trihydrate demonstrates a very low solubility in water but is considered to be amphoteric, meaning it will dissolve in both acids or a strong alkali. The most common use of Alumina Trihydrate is for the production of aluminum metal. It is also used as a flame retardant and smoke suppressant filler in polymers such as rubber products and carpet backing.
