Corundum. There are a few forms of aluminum oxide, and corundum being the most common. The structure of corundum can be viewed as a hexagonal close packed array of oxygen atoms with 2 / 3 of the octahedral sites occupied by Al 3 + ions. Thus, the Al 3 + ions are bonded to 6 oxygen in a distorted octahedron. Each such octahedron share …Web
