The compound is used as a desiccant (to keep things dry by adsorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water. It is made of aluminium oxide (alumina; Al 2 O 3). It has a very high surface-area-to-weight ratio, due to the many "tunnel like" pores that it has.
Aluminium is also good at reflecting solar radiation, although prolonged exposure to sunlight in air adds wear to the surface of the metal; this may be prevented if aluminium is anodized, which adds a protective layer of oxide on the surface. The density of aluminium is 2.70 g/cm 3, about 1/3 that of steel, much lower than other commonly ...

Aluminum silicate (or aluminium silicate) is a name commonly applied to chemical compounds which are derived from aluminium oxide, Al 2 O 3 and silicon dioxide, SiO 2 which may be anhydrous or hydrated, naturally occurring as minerals or synthetic. Their chemical formulae are often expressed as xAl 2 O 3 ·ySiO 2 ·zH 2 O. It is known as E ...
Aluminium(I) oxide (Al 2 O) Aluminium(II) oxide ( AlO ) (aluminium monoxide) Aluminium(III) oxide (aluminium oxide), ( Al 2 O 3 ), the most common form of aluminium oxide, occurring on the surface of aluminium and also in crystalline form as corundum , sapphire , and ruby .
The crystal is orthorhombic, with a density of 3067 kg·m −3. It reacts rapidly with water. It reacts rapidly with water. Tetracalcium trialuminate , 4CaO·3Al 2 O 3 ( C 4 A 3 ), is a metastable phase formed by dehydrating 4CaO·3Al 2 O 3 ·3H 2 O ( C 4 A 3 H 3 ).
