What are some uses for Corundum?
Corundum is commonly used as an abrasive material in products like sandpaper and grinding wheels due to its hardness. It is also used as a gemstone, with varieties such as ruby and sapphire being highly valued for jewelry. Additionally, corundum-based ceramics are used in various industrial applications due to their high thermal and chemical resistance.
What color is corundum?
***Pure corundum is transparent and colorless but most specimens contain some transition elements substituting for aluminum, resulting in the presence of color. Substitution of Chromium results in a deep red color; such red corundum is known as ruby.corundum is a dark red, blue and yellow colors
Is corundum magnetic?
Small traces of iron are responsible for much of the color found in corundum (saphire) gems. Ruby, however, does not contain iron and will not be affected by a magnet. To be technical however, I should point out that corundum is not magnetic. Corundum will not attract other pieces of iron to itself (as far as I know). To simply answer that corundum is not magnetic would have been misleading.
