Alumina is a stable oxide of aluminum with the chemical formula Al2O3. It is also called bauxite in mining, ceramics and materials science. Properties: White solid that is difficult to dissolve in water, odorless, tasteless, extremely hard, easily absorbs moisture but does not deliquesce (it does not absorb moisture after burning). Aluminum oxide is a typical amphoteric oxide (corundum is α-shaped and belongs to the hexagonal closest packing. It is an inert compound, slightly soluble in acid and alkali and resistant to corrosion[1]). It can be soluble in inorganic acids and alkaline solutions, and is almost insoluble in water. And non-polar organic solvents; relative density (d204) 4.0; melting point 2050°C. Storage: Store in a sealed and dry container. Usage: Used as analytical reagents, dehydration of organic solvents, adsorbents, organic reaction catalysts, abrasives, polishing agents, raw materials for smelting aluminum, and refractory materials.

Application

Alumina of 99.99 percent purity are mainly used in making special ceramics, high pressure sodiumlamps,fluorescent,catalyst carriers and special grinding materials.
