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 the hexagonal densest packing. It is a corrosion-resistant, inert material that is only slightly soluble with acid and alkali. Aluminum oxide dissolves in alkaline or inorganic solutions 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.
Non-metallurgical Aluminium Oxide is available in more than 300 different types, with many uses and excellent chemical and physical properties. The price of this non-metallurgical product is also much higher than the price of metallurgical.
Due to its excellent properties such as high melting point and hardness, high electrical resistivity, good mechanical characteristics, wear resistance, corrosion resistant, green heat resistance, and others, ultra-fine high-purity aluminum oxide can be used for a variety of applications including: light-transmitting sintered bodies and phosphors carriers; advanced porcelains; artificial bones; semiconductors and integrated circuit substrates; audio tape fillers and catalysts.
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 and some other materials. 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 a hard compound that has the chemical formula Al2O3. Alumina, an amphoteric alloy, can be reacted with acid or alkali in order to produce aluminate.Aluminum oxide is the typical amphoteric compound (corundum has an alpha shape and belongs to the hexagonal densest packing.

Applications of Aluminum Oxide
More than 90% of the aluminum oxide used for electrolytic aluminum is aluminum oxide. But many other sectors, such as electronics and petroleum, as well as chemicals, ceramics and plastics, textiles and papermaking, as well as pharmaceuticals, also need oxidation.Non-metallurgical Aluminium Oxide is available in more than 300 different types, with many uses and excellent chemical and physical properties.
