What is the crystal form of corundum?
6 sided with a square figure
What is the breakage of corundum?
Corundum has a brittle fracture, which means it tends to break into sharp, irregular fragments. This is due to the strong atomic bonding within the crystal structure of corundum, which results in the propagation of cracks rather than plastic deformation.
What do bauxite and corundum have in common?
Bauxite and corundum are both aluminum minerals. Bauxite is the primary ore of aluminum from which aluminum is extracted, while corundum is a naturally occurring crystal form of aluminum oxide known for its hardness and use in abrasives.
What crystal has a hardness of 9?
The crystal with a hardness of 9 on the Mohs scale is corundum, which includes varieties such as sapphire and ruby. Corundum is known for its exceptional durability and is commonly used in jewelry and industrial applications. Its high hardness makes it suitable for cutting tools and abrasives as well.
Does corundum have cleavage or fracture?
Corundum does not exhibit cleavage; instead, it has a conchoidal to uneven fracture. Cleavage refers to the tendency of a mineral to break along specific planes of weakness, while corundum's strong crystal structure results in a lack of such planes. Therefore, when corundum breaks, it does so irregularly rather than along defined lines.
Is corundum hexagonal or cubic?
Corundum ( (Al_2O_3) ) is hexagonal in crystal structure.
What is the crystal form of corundum?
6 sided with a square figure
What is the scientific name for a ruby?
The scientific name for a ruby is corundum. Rubies are a variety of the mineral corundum that get their red color from trace amounts of chromium present in the crystal structure.
Is ruby a type of crystal?
No, Ruby is not a type of crystal like quartz or amethyst. Ruby is a precious gemstone made of red corundum, a mineral form of aluminum oxide. It is prized for its deep red color and often used in jewelry.

What is the transparency of corundum?
Corundum is transparent as a mineral, especially in its gemstone forms such as sapphire and ruby. The level of transparency can vary depending on the quality and any inclusions present in the crystal structure. In general, corundum is prized for its transparency and clarity when cut and polished as a gemstone.
What are the eight ways to identify corundum?
THE EIGHT WAYS TO I.D. A MINERALThe eight ways to identify a mineral such as corundum are 1 hardness 2 crystal shape 3 special features 4 density 5 streak 6 luster 7 cleavage or fracture 8 color. (to find out hardness look up "Mohs scale of hardness" everything else you could search it on google or bing)

Therefore, when corundum breaks, it does so irregularly rather than along defined lines.
What is the crystal structure of a sapphire?
Sapphire typically has a hexagonal crystal structure, with aluminum oxide (Al2O3) forming a dense, closely packed arrangement of oxygen and aluminum ions. This crystal structure contributes to sapphire's hardness and durability, making it a popular choice for jewelry and industrial applications.
What are sapphires formed from?
Sapphires are formed when heat and pressure are applied to the mineral corundum. A sapphire can be any color but red. Impurities introduced in to the corundum during crystal formation dictate the final gemstone color.
