Why is corundum magnetic?
Corundum, also known as aluminum oxide, is not magnetic. It is a diamagnetic material, meaning it does not have any magnetic properties and is very weakly repelled by magnetic fields.
Which gemstones contain aluminium oxide?
Gemstones such as sapphire and ruby contain aluminum oxide, also known as corundum. Corundum is one of the hardest minerals and is commonly used in jewelry due to its durability and vibrant colors.
Is corundum a silicate?
No, corundum is not a silicate. It is a mineral composed of aluminum oxide. Silicate minerals, on the other hand, are composed of silicon and oxygen.
