Corundum - Crystalline Aluminium Oxide (Al2O3) is a mineral that is hard (9.0 on Mohs scale) and used as an abrasive.
No, a mineral is a hard substance
Very soft mineral
easy
Mineral hardness is measured by how resistant one mineral is to being rubbed against another. If the mineral displays clear abrasion then it has low hardness whereas if it displays little abrasion it is a hard mineral.
It's pretty freakin hard!
Corundum is a very hard mineral used as an abrasive in industry.
An abrasive mineral is a hard material used to wear away or remove surface layers through friction. Common examples include garnet, emery, and quartz. They are often used in processes like sandblasting, grinding, and polishing.
A solid abrasive material is a mineral which can wear away part of another solid by rubbing. A common solid abrasive is diamond.
Pumice
A solid abrasive material is a mineral which can wear away part of another solid by rubbing. A common solid abrasive is diamond.
garnets The abrasive grain, the key part of coated abrasive products, may be either a natural or synthetic mineral. Due to their extreme hardness, natural minerals such as http://www.answers.com/topic/garnet, quartz or http://www.answers.com/topic/emery (corundum with iron impurities) have uses in sandpaper and grinding tools.
corundum
because it is hard
Corundum is a mineral with a hardness of 9 on the Mohs scale. It is used as an abrasive and is also the mineral form of aluminum oxide. Sapphire and ruby are gem varieties of corundum.
Aluminum oxide is commonly used as an abrasive in various industries. It is known for its hardness and the ability to cut through materials effectively.
Diamond is a very hard white mineral.
