α-?alumina, calcined alumina (known as corundum) is the most stable in the alumina phase, its stability and its crystal structure has a close relationship with alumina belongs to A2B3 type compounds, alpha alumina is the three party system, a0=0.475nm, c0=1.297nm, in the structure of oxygen atoms into the six most densely packed and aluminum atoms are filled in the gaps in the surface of the body eight. Because the ratio of aluminum atoms to oxygen atoms is 2:3, the aluminum atoms do not fill all the voids of the eight faces, only fill in 2/3, thus reducing the symmetry of α- alumina crystals. In the α- alumina crystal structure, 3 oxygen atoms from the surface is eight surface adjoining the total, the crystal can be seen as countless eight surface [AlO6] through the combination of coplanar "molecules", this structure makes the stability of α- alumina.

In the lattice of calcined alumina, the oxygen ions are closely packed in six sides, and Al3+ is symmetrically distributed in the coordination center of the eight surface of the oxygen ions. Calcined 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; high purity calcined alumina or artificial corundum, production synthetic ruby and sapphire material; also used in plate production base of modern large scale integrated circuit.
