CAS No.1344-28-1
Alias: AluminumOxide,Neutral,BrockmannActivityGradeI;AluminumOxide,Basic,BrockmannActivityGradeI;Aluminumoxide,Drysphere?desiccant,WitChemicalbookhoutindicator;AluminumOxide,Neutral-H15152;AluminaB,Active;AluminaA,Activity:I;AluminaA,Activity:SuperI;AluminaB,Activity:SuperI
Molecular formula: Al2O3
Relative molecular mass: 101.96
Structural formula:
1. Performance and use:
Aluminum Oxide (Alumina) is the most widely used oxide, chiefly because it is plentiful, relatively low in cost, and equal to or better than most oxides in mechanical properties. Density can be varied over a wide range, as can purity-down to about 90% alumina-to meet specific application requirements. Alumina ceramics are the hardest, strongest, and stiffest of the oxides.
They are also outstanding and with electrical resistivity and dielectric strength, are resistant to a wide variety of chemicals, and are unaffected by air, water vapor, and sulfurous atmospheres. However, with a melting point of only 2039°C, they are relatively low in refractoriness and at 1371°C retain only about 10% of room-temperature strength.
In addition to its wide use as electrical insulators and its chemical and aerospace applications, the high hardness and close dimensional tolerance capability of alumina make this ceramic suitable for such abrasion-resistant parts as textile guides, pump plungers, chute linings, discharge orifices, dies, and bearings.
Aluminum oxide is known as the mineral bauxite. Its main use is for the production of aluminum metal by electrolysis. It is also used in many other chemical reactions.
As adsorbent, desiccant, abrasive,thickening and anti-caking agent;
As filler for paints and varnishes;
In manufacture of alloys,refractories, ceramic materials, electrical insulators and resistors, dental cements, glass, steel, artificial gems; in coatings for metals, etc.;
As catalyst for organic reactions.
As an insoluble carrier for mineral pigment, and is frequently mixed into mineral powder makeup. Because of its abrasive texture, many use these crystals to exfoliate and resurface the skin-particularly with Microdermabrasion.
As a chromotagraphic matrix; originally called Brockmann aluminum oxide when used for this purpose.
The minerals corundum (hardness = 9) and Alundum (obtained by fusing bauxite in an electric furnace) are used as abrasives and polishes;
In manufacture of cosmetic products like blush, powder foundation, lipstick and facial cleanser.

3. Packaging and storage
Aluminum oxide should be stored in a well-closed container in a cool, dry, place. It is very hygroscopic.4. Safety protection
Suspected carcinogen with experimental neoplastigenic and tumorigenic data by implantation. Inhalation of finely divided particles may cause lung damage (Shaver's disease). Exothermic reaction above 200℃ with halocarbon vapors produces toxic HCl and phosgene. See also ALUMINUM COMPOUNDS
