Aluminum hydroxide hydrate
Aluminum hydroxide hydrate (CAS 1330-44-5), with the chemical formula Al(OH)3 · xH2O, is a versatile inorganic compound. Supplied as a white powder, it plays a crucial role in various industrial applications. Its primary uses include acting as a flame retardant, a precursor for other aluminum compounds, and a raw material in the production of glass and ceramics. This hydrated form offers specific advantages in processes requiring controlled release of alumina.
Flame Retardant Additive
Aluminum hydroxide hydrate is widely used as a non-halogenated flame retardant in polymers and plastics. Upon heating, it decomposes endothermically, releasing water vapour which cools the material and dilutes combustible gases.
Chemical Intermediate
It serves as a key intermediate in the synthesis of various aluminium salts, zeolites, and activated alumina. These downstream products find applications in catalysis, water treatment, and chemical manufacturing.
Glass and Ceramics Manufacturing
Incorporated into glass and ceramic formulations, aluminum hydroxide hydrate contributes to improved thermal shock resistance, chemical durability, and mechanical strength of the final products.
Filler and Pigment
In certain applications, it functions as a white filler or pigment, enhancing opacity and providing desirable physical properties to materials such as paints and coatings.
