Aluminum oxide
Al2O3 has the chemical formula Al2O3. Aluminum oxide, also known as bauxite, is used in materials science and ceramics.
Aluminum oxide is the typical amphoteric compound (corundum has an alpha shape and belongs to hexagonal packing). It is corrosion resistant, inert and slightly soluble in alkali and acid. Aluminum oxide dissolves in inorganic alkali and acids, but is insoluble in water or non-polar organic solvents.
Alumina has over 10 homogeneous crystalline types. These include gAl2O3,bAl2O3,and aAl2O3 corundum. Different structures are characterized by different properties. They almost entirely transform into a – Al2O3 when heated above 1300degC.
There are over 300 different types of nonmetallurgical oxides, all of which have excellent chemical and physical properties. They also have a variety of uses. However, the prices of these oxides are much higher than those of metallurgical oxides.
Due to its excellent properties such as high melting point and hardness, excellent mechanical properties, wear and corrosion resistance, green heat resistant, and good mechanical characteristics, ultra-fine high-purity aluminum oxide can be used in a variety of applications including: light-transmitting sintered bodies, phosphors carrier, advanced porcelains, artificial bones and teeth, semiconductors, integrated substrates for circuits, audio tapes fillers and catalysts, laser materials or cutting tools.
Aluminum oxides with a purity of 99.995% are mainly used in the production of artificial sapphire for LEDs. They can also be used to produce advanced ceramics, PDPs and high-performance material. The raw material for sapphire crystal can be powder, granules or blocks, depending on the requirements.
99.99% high purity aluminum oxide is used mainly in high pressure sodium lamps, new luminescents materials, special coatings, three primaries colors, catalysts and high performance materials.

Aluminum Oxide Properties
Alumina (aluminium dioxide) is an inorganic compound with the chemical formula Al2O3, and is of high hardness. Alumina, an amphoteric alloy, can be reacted with alkali and form aluminate or it can be reacted with acid to produce aluminum salt of that acid.Aluminum oxide is the typical amphoteric compound (corundum has an alpha shape and belongs to hexagonal packing). It is corrosion resistant, inert and slightly soluble in alkali and acid. Aluminum oxide dissolves in inorganic alkali and acids, but is insoluble in water or non-polar organic solvents.

Applications of Aluminum Oxide
Aluminum oxide is the main raw material used for electrolytic aluminum production. But many other sectors, such as electronics and petroleum, as well as chemicals, ceramics, plastics textiles, papermaking and pharmaceuticals need oxidation to have special properties.There are over 300 different types of nonmetallurgical oxides, all of which have excellent chemical and physical properties. They also have a variety of uses. However, the prices of these oxides are much higher than those of metallurgical oxides.
