Detailed Introduction

Aluminium hydroxide, Al(OH)3, is found in nature as the mineral gibbsite. Aluminium hydroxide is amphoteric in nature, it has both basic and acidic properties. Closely related are aluminium oxide hydroxide, and aluminium oxide or alumina (Al2O3), the latter of which is also amphoteric. These compounds together are the major components of the aluminium ore bauxite.


Uses

Fire retardant filler

Aluminium hydroxide also finds use as a fire retardant filler for polymer applications.  it is colorless (like most polymers), inexpensive, and has good fire retardant properties. it is very effective as a smoke suppressant in a wide range of polymers, most especially in polyesters, acrylics, ethylene vinyl acetate, epoxies, PVC and rubber.

 

Precursor to Al compounds

Aluminium hydroxide is a feedstock for the manufacture of other aluminium compounds: speciality calcined aluminas, aluminium sulfate, polyaluminium chloride, aluminium chloride, zeolites, sodium aluminate, activated alumina, and aluminium nitrate.
