Often referred to as alumina, aluminium oxide is an ionic compound that contains both metal and non-metal. It can be used in a wide variety of applications.
It is an amphoteric compound, which means that it reacts with both bases and acids. Aluminium oxide is also an electrical insulator. It forms a thin white coating on metallic aluminium, which helps prevent further oxidation.
The crystalline form of aluminium oxide is used in many applications, including as an abrasive. It is also used as a fire retardant and in the manufacture of ceramics and refractories. A variety of glass formulations contain aluminium oxide. It is also used in many cosmetic applications.
Aluminium oxide is also used to create bulletproof windows. It is also an important component of bionic implants. It is also a popular filler in plastics. It is also a common ingredient in sunscreen. It is also used as a substrate for integrated circuits.
Aluminium oxide has many uses, including as an abrasive and an electrical insulator. It is also used to create body armour and vehicle armour. It is also used in the medical industry as a prosthetic eye substitute.
It is a very reactive compound with atmospheric oxygen. It is used in ceramics, refractories, and as a coating for high-wear areas. It is also used in the manufacture of insulation for high-temperature furnaces.
Aluminium oxide is a very important component in the production of aluminium metal. It also serves as a catalyst for many useful industrial reactions.
