Alumina
Alumina, chemical symbol Al2O3, molecular weight 102, pure alumina is a white amorphous powder, commonly known as bauxite, the density of 3.9-4.0g/cm3, the melting point of 2050 DEG C, the boiling point of 2980 DEG C, insoluble in water, is an amphoteric oxide, soluble inorganic acid and alkaline solution, there are four kinds of an isomer of delta beta alumina V - A - alumina alumina alumina, mainly alpha and gamma type two variants, the industry can be extracted from bauxite.

In the lattice of alpha alumina, the oxygen ions are closely packed in six sides, and the Al3+ is symmetrically distributed in the coordination center of the eight surface surrounded by oxygen ions. Alpha alumina insoluble in water and acid, also known as alumina industry, is the basic raw material of aluminum; also used for all kinds of refractory bricks, refractory crucible, refractory, high temperature resistant experiment instrument; can also be used as a polishing agent, flame retardant agent and filler; a type of high purity alumina or artificial production artificial corundum, ruby and sapphire materials; also for plate production base of modern large scale integrated circuit.

Alumina is aluminum hydroxide in low temperature 140-150 degrees Celsius under dehydration, the industry also called activated alumina, aluminum hydroxide. In the structure, the oxygen ion is close to the close packed cubic face, and the Al3+ is irregularly distributed in the eight planes and the tetrahedral voids surrounded by oxygen ions. Gamma alumina is insoluble in water, soluble in strong acid or alkali solution, heated to 1200 DEG C, it is converted into alpha alumina. Gamma alumina is a porous material, the surface area per gram of up to several hundred square meters, high adsorption capacity. Industrial products are often colorless or microstrip pink cylindrical particles, good pressure resistance. In oil refining and petrochemical industry is a commonly used adsorbent, catalyst and catalyst carrier; in industry is the acid removal agent of transformer oil, turbine oil, also used for chromatographic analysis in the laboratory is neutral; strong desiccant, the drying capacity is not less than the use of phosphorus pentoxide, after repeated use in 175 DEG 6-8h also heating regeneration.

At present, the alumina produced by Bayer process in the world accounts for more than 90% of the total output, and most of the alumina is used to make aluminum metal, which is less than 10% of other uses.
