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 is inert. It is slightly soluble both in acid and in alkali. And it is resistant to corrosion). Aluminum oxide dissolves in inorganic alkaline solutions and in inorganic acids, but is insoluble in water.
Alumina has over 10 homogeneous crystalline types. These include gAl2O3,bAl2O3,and a-Al2O3(corundum). Different structures are characterized by different properties. They almost entirely transform into a – Al2O3 when heated above 1300degC.
Currently, there are over 300 different types of nonmetallurgical oxide. They all have excellent chemical and physical properties. Their price is higher than the price for metallurgical oxide.
Due to its excellent properties such as high melting point and hardness, wear resistance and corrosion resistance, ultra-fine high-purity aluminum oxide can be used for a variety of applications including: light-transmitting sintered bodies, phosphors carrier, single-crystal materials, advanced porcelains, artificial bones and teeth, semiconductors and integrated circuit substrates.
The high-purity series of aluminum oxides with a purity of 99.995% is mainly used in the production and processing for LED artificial crystals, PDP PDPs, high-performance ceramics, etc. 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, advanced coatings. Three primary colors are also used, as well as catalysts and high performance materials.

Aluminum Oxide Properties
Alumina (aluminium dioxide) is a hard compound that has the chemical formula Al2O3. Alumina, an amphoteric alloy, can be reacted with alkali and form aluminate or it can be reacted with acid to produce aluminum salts.Aluminum oxide is the typical amphoteric compound (corundum has an alpha shape and is inert. It is slightly soluble both in acid and in alkali. And it is resistant to corrosion). Aluminum oxide dissolves in inorganic alkaline solutions and in inorganic acids, but is insoluble in water.

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 and plastics, textiles and papermaking as well as pharmaceuticals require oxidation to have special properties.Currently, there are over 300 different types of nonmetallurgical oxide. They all have excellent chemical and physical properties. Their price is higher than the price for metallurgical oxide.
