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 an inorganic compound with the chemical formula Al2O3, and is of high hardness. Alumina, an amphoteric alloy, can be reacted with acid or alkali in order to produce aluminum salts.
Aluminum oxide is the typical amphoteric compound (corundum has an alpha shape and is part of the hexagonal densest packing. It is an inert material, is slightly soluble in alkali and acid, and is corrosion resistant). Aluminum oxide dissolves in alkaline or inorganic solutions but is insoluble in water.

Alumina is made up of over 10 crystals. There are three main types: gAl2O3,bAl2O3,and aAl2O3(corundum). Different structures are characterized by different properties. They almost completely transform into a -Al2O3 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, plastics (refractories), textiles, papermaking or pharmaceuticals, 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 metallurgical version.

Due to its excellent properties such as high melting point and hardness, corrosion resistance and wear resistance, 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 integrated circuits, audio tapes 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 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, advanced coatings. Three primary colors are also used, as well as catalysts, and high performance materials.
