Corundum represents the crystalline form of aluminium oxide. It is a pure material characterized by high level of hardness, with a regular shape and allochromatic properties. Its colour depends on impurity that do not alter its chemical composition.

Last but not least, corundum is used in the ceramic sector as anti-slip and anti-wear additive for glazes for floor tiles and in the production of ceramic items thanks to its surface hardness.
