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 hexagonal in structure, it is inert and slightly soluble in alkali and acid, and is corrosion resistant). 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 aAl2O3(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 and can be used in a variety of ways. The price of this aluminum oxide is also much higher than the price of metallurgical oxide.
Due to its excellent properties such as high melting point and hardness, wear resistance, corrosion, and green heat resistance, ultra-fine high-purity aluminum oxide can be used for a variety of applications including: light-transmitting sintered bodies, 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 and other materials. The raw material for sapphire crystal can be powder, block, granule or column depending on the requirements.
99.99% high purity aluminum oxide is used primarily 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 an organic substance with the chemical Formula Al2O3 that is a compound 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 salts.Aluminum oxide is the typical amphoteric compound (corundum has an alpha shape and is hexagonal in structure, it is inert and slightly soluble in alkali and acid, and is corrosion resistant). Aluminum oxide dissolves in alkaline or inorganic solutions but is insoluble in water.

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, plastics or textiles as well as papermaking, pharmaceuticals, and refractories also need oxidation.Currently, there are over 300 different types of nonmetallurgical oxide. They all have excellent chemical and physical properties and can be used in a variety of ways. The price of this aluminum oxide is also much higher than the price of metallurgical oxide.
