This is an aluminum stable oxide. The chemical formula for it is Al2O3. Aluminium oxide can also be called “bauxite” in ceramics, mining and materials science.
Aluminum Oxide Properties
Alumina is an organic compound with the chemical composition Al2O3 that is high in hardness. Alumina, an amphoteric dioxide, can react to alkali to create aluminate and can also react to acid to produce aluminum salt.
Aluminium oxide is a common amphotericoxide (corundum is alpha-shaped. It belongs to the hexagonal densesest packing.) Aluminum oxide is an inert chemical, slightly soluble with acid and alkali. And it is also resistant to corrosion. Aluminum oxide dissolves in organic acids and alkaline solutions but it is nearly insoluble in water.
Alumina contains more than 10 homogeneous Crystals. These include g, b, and a Al2O3 (corundum) crystal types. The properties of different structures are very varied and at temperatures higher than 1300degC, they can almost be transformed completely into a Al2O3.
Applications of Aluminum Oxide
Today, aluminum oxide makes up more than 90%. But many industries such as petroleum, chemical, refractories and electronics require an oxidation process with special properties.
At the moment, more than 300 varieties of non-metallurgical Aluminum Oxide exist. They each have excellent physical and chemical characteristics, broad uses and a much lower price than metallurgical.
One example is high-purity ultrafine aluminum oxide. This high melting temperature, hardness and electrical resistance makes it a popular choice for single crystal materials and phosphors Carriers.
It is mostly used to make LED artificial sapphires crystals, advanced ceramics as well as PDP phosphors. The raw material used to make sapphire-crystal can be made into powder, blocks, and granules depending on the requirements.
These high-purity 99.99% aluminum oxides are used mostly in high-pressure sodium lamps and new luminescent materials. They also make up some of the most high-performance materials.
