A Corundum aluminum oxide manufacturer will offer various kinds of corundum. This material is
the second-hardest mineral in the world, after diamond. Because of its high hardness, corundum
is commonly used as an internal coating for frosted light bulbs. The hardness of materials is
measured on a Mohs scale, from one to ten. This particular material has a hardness of 8.8.

The crystalline form of aluminum oxide is called corundum. The color of corundum is the result
of trace impurities within its structure. The color of a sapphire or a ruby is a result of trace
amounts of chromium. Other types of corundum are used as components in cutting tools, and
are found in many natural settings. In addition, these materials are used in the production of
microchips.
