Aluminum oxide Al2O3 has the chemical formula Al2O3. Aluminum oxide, also known as bauxite, is used in materials science and ceramics.

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 in order to produce the aluminum salt of that acid.
Aluminum oxide is the typical amphoteric compound (corundum has an alpha shape and belongs to a hexagonal dense packing. It is an inert material, slightly soluble both in acid and in alkali solutions, and resistant to corrosion). Aluminum oxide dissolves in alkaline or inorganic solutions but is insoluble in water.

Alumina consists of over 10 crystals. There are three main types: gAl2O3,bAl2O3,and aAl2O3(corundum). Different structures are characterized by different properties. They almost entirely transform into a -Al2O3 when heated above 1300degC.

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 or papermaking, also need oxidation.

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. The price of these oxides is significantly higher than the price of metallurgical oxide.

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 phosphor carriers, single crystal materials and advanced porcelain, artificial bone, semiconductors, integrated-circuit substrates, audio-tape fillers, catalysts and their carriers.

Aluminum oxides with a purity of 99.995% are mainly used in the production of artificial sapphire, PDP, ceramics and high-performance material. The raw material for sapphire crystal can be powder, granules or blocks, depending on the requirements.

The 99.99% high purity aluminum oxide series can be used in many applications, including high pressure sodium lamps, special ceramics or coatings, 3 primary colors and catalysts.
