Corundum is a naturally occurring mineral composed of aluminum oxide (Al₂O₃) and can form through various geological processes. It typically crystallizes under high-pressure and high-temperature conditions within metamorphic rocks or as a result of the cooling of magma. Additionally, synthetic corundum can be produced in laboratories through methods like the Verneuil process or the Czochralski process, where aluminum oxide is melted and allowed to crystallize. These processes create both natural and synthetic forms of corundum, which includes gemstones like sapphires and rubies.

What object is made up of corundum?
An abrasive material called emery is made up of corundum, which is a naturally occurring form of aluminum oxide. Corundum is a very hard mineral that is commonly used in abrasives for grinding, cutting, and polishing applications due to its durability and hardness.
What is the plural of corundum?
Corundum.
What is ruby made of?
Rubies are a variety of corundum, the mineral name for aluminum oxide, Al2O3. The red color comes from trace amounts of chromium.
What are rubies made of?
Rubies are made of the mineral corundum, which is composed of aluminum oxide with the element chromium giving the gemstone its red color. The intensity and shade of red in rubies can vary based on the amount of chromium present in the crystal structure. Inclusions of other minerals or elements can also affect the ruby's appearance and value.
Which crystal system does corundum have?
Corundum is in the trigonal crystal system.
