What is it?
Aluminium oxide (or alumina) is a chemical compound of aluminium and oxygen. Ceramic aluminium oxide at various levels of purity is the most important oxide used in ceramics.
How it is made
Aluminium oxide is usually produced industrially from bauxite, and it has numerous applications, thanks to a series of chemical and physical properties that make it suitable for a range of uses.
Use
Aluminium oxide is the most well-known and commonly used advanced ceramic material, because it combines the basic properties of several materials of this type. It is therefore used in a large number of fields such as electronics and mechanics, and also in medicine as a material for grafts.
