Aluminium hydroxide, Al(OH)₃, Alum, is the most stable form of aluminium in normal conditions. It is found in nature as the mineral gibbsite (also known as hydrargillite) and its three, much more rare, polymorphs: bayerite, doyleite and nordstrandite.

Applications:

1. Aluminium hydroxide also finds use as a fire-retardant filler for polymer applications. It is selected for these applications because it is colorless (like most polymers), inexpensive, and has good fire-retardant properties.
2. 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.
3. Under the generic name "algeldrate", aluminium hydroxide is used as an antacid in humans and animals (mainly cats and dogs). It is preferred over other alternatives such as sodium bicarbonate because Al(OH)₃, being insoluble, does not increase the pH of stomach above 7 and hence, does not trigger secretion of excess acid by the stomach.
