Description and Uses

Aluminum hydroxide, insoluble in water, soluble in dilute mineral acids and alkali hydroxides (4 % suspension in water), white, amorphous powder. For other relevant properties and production, see→Aluminum Oxide, Chap. 1.1. Available as Al(OH)3·nH2O (algedrate) and algedrate hexitol complex.

As absorbent, in chromatography, manufacturing of glass, paper, inks, ceramics, lubricants, cosmeticsAluminum hydroxide is used as a desiccant powder, filler in paper, plastics, rubber and cosmetics. It is used as a smoke suppressant and mordant dye. It is also used in drugs as antacid and antihyperphosphatemic. It is also used as a Claus catalyst support for waterproof fabrics. It is an important starting material for the preparation of other aluminum compounds, calcined alumina, aluminum sulfate, polyaluminum chloride, zeolites, sodium aluminate, activated alumina and aluminum nitrate. In addition, it is used as a fire retardant.
