The formula for corundum is Al 2 O 3.The corundum structure consists of hexagonal close packed (a close packing) O atoms, with Al filling up 2/3 of the central octahedral sites. The Al atoms occur two in a row, then skip a site. This pattern is staggered for adjacent rows. Corundum is found in metamorphic rocks, including in aluminum-rich limestone near the seashore which has been …

Corundum has a hardness of 9 on Moh's Scale, which makes it the second hardest material known. When ground with haematite, magnetite and spinel it is used to make emery, which is a very good abrasive. Although corundum is second only to diamond in hardness, it makes a poor substitute. Diamond is over four times as hard as corundum.

Ruby and sapphire (usually blue, but also in every other color) have been the most important colored gemstones for several thousand years. Originating historically in southeast and central Asia, and more recently in eastern Africa, these colored varieties of the mineral corundum have been much sought as gems because of their rarity, color and durability. Gem corundum can …
The conditions for the synthesis of mullite-corundum ceramic prepared on the basis of Al2O3 and SiO2 powders were investigated. The composition of mullite-corundum ceramic with Al2O3 < 80 wt.%, which affords the best thermomechanical compatibility with molybdenum, was determined. The possibility of obtaining a composite material based on a …
Natural corundum shows two types of twins: "basal twin", by reflection on (0003) pinacoid, very rare, and "rhombohedral twin", by reflection on ( $$10overline{1 }1$$ 10 1 ¯ 1 ), more frequent. The analysis of the structural continuity across the composition plane does not show any reason for a large difference in occurrence frequency, which is likely related to the …
