Aluminum Hydroxide

Aluminum Hydroxide Aluminum Hydroxide obtained from bauxite by the Bayer process has the chemical formula AL(OH)3 or Al2O3,3H2O. It has very high reactivity to acid and alkali. And as it is stable up to approximately 200°C and absorbs much of heat while the water if crystallization is dehydrated at higher temperature, it is used widely for flame retarders. It is used in a wide range of industrial application by free moisture content and standard particle size.
