aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula al₂o₃. with the cas registry number 1344-28-1, it is also named as activated aluminum oxide. the product's categories are industrial / fine chemicals; inorganics; alumina & aluminum hydroxide tlc adsorbents; bulk adsorbents for tlc; thin layer chromatography (tlc); al; aluminum materials science; nanomaterials materials science; metal and ceramic science; nanoparticles: oxides, nitrides, and other ceramics nanomaterials; oxides, and the other registry numbers are 107462-07-7; 107874-14-6; 122784-35-4; 12522-88-2; 127361-04-0; 12737-16-5; 131689-14-0; 135152-65-7; 135667-70-8; 138361-58-7; etc. besides, it is white odorless crystalline powder, which should be stored in dry, ventilated warehouse. in addition, its molecular formula is al₂o₃ and molecular weight is 101.96.

the other characteristics of aluminum oxide can be summarized as: (1)einecs: 215-691-6; (2)refractive index: 1.765; (3)h-bond donor: 0; (4)h-bond acceptor: 3; (5)rotatable bond count: 0; (6)exact mass: 101.947821; (7)monoisotopic mass: 101.947821; (8)topological polar surface area: 43.4; (9)heavy atom count: 5; (10)complexity: 34.2; (11)density: 3.95-4.1 g/cm³; (12)melting point: 2072 °c; (13)boiling point: 2977 °c; (14)flash point: 2980 °c; (15)vapor pressure: 17 mm hg ( 20 °c).

preparation of aluminum oxide: aluminum oxide can be prepared by calcining of bauxite.
2 al(oh)₃ → al₂o₃ + 3 h₂o
the reaction consists several phases of alumina rather than solely corundum.

uses of aluminum oxide: aluminum oxide is used as a filler that is a common ingredient in sunscreen. it is also used as a catalyst and catalyst support for the manufacture of many industrial catalysts. what's more, it is used to remove water from gas streams. and it can be used as a coarse or fine abrasive. in dentistry, it is also used as a polishing agent to remove stains. it is used as a material in hip replacements in health and medical applications. furthermore, it can be used as a medium for chromatography, a dosimeter for radiation protection and therapy applications for its optically stimulated luminescence properties in laboratory. and it is used in the fabrication of superconducting devices. similarly, it can be used to purify bauxite.
al₂o₃ + 3 h₂o → 2 al(oh)₃

when you are using aluminum oxide, please be cautious about it as the following: it is highly flammable. please keep away from sources of ignition. moreover, it is irritating to eyes, respiratory system and skin. in case of contact with eyes, rinse immediately with plenty of water and seek medical advice. and you should wear suitable protective clothing to avoid contact with skin and eyes. additionally, its apours may cause drowsiness and dizziness. please keep container tightly closed.
