Generally, aluminium oxide, also called ala2o3, is the oxide of aluminum. It is an alkaline earth chemical compound with three oxygen atoms and has a melting point of 2980 degC. It is widely used in various fields.
Aluminium oxide is the preferred material for prosthetic eye substitutes, and it is also used in a variety of applications including bionic implants, cutting tools, medical devices, and water filters. It is also used as a filler in bricks, heavy clayware, and plastics.
Aluminium oxide has a relatively high melting point and boiling point, which makes it suitable for the construction of high-temperature appliances. It is also used in the manufacture of a variety of commercially important chemicals.
The chemical structure of aluminium oxide consists of three oxygen atoms and a series of vacancies. It is insoluble in water and most organic solvents. It has a very low electrical conductivity.
It is usually found in crystalline form, but it can also be in non-crystalline form. The most common crystalline form of aluminium oxide is corundum. Corundum has a trigonal bravais lattice with a space group of R-3c. Corundum is also commonly found in gem-quality forms, such as sapphires.
Aluminum oxide is often used as an abrasive, particularly in grinding and cutting operations. It can be used in sandpaper, and in various types of scratch-repair kits. It is also used in ceramics and paint for decorative effects. It is also used in the production of adsorbents, catalysts, and other chemicals.
