Alumina is, arguably, the most widely-used advanced ceramic material, and it is made from the naturally-occurring ore called bauxite by implementing the process of Bayer extraction. The chemical compound of bauxite contains both oxygen and aluminium molecules.
Once aluminium oxide is extracted from bauxite, it looks similar to a regular white powder. For example, other forms of alumina that occur freely in nature are precious gems of ruby and sapphire.
Alumina advanced ceramic can be produced implementing several different manufacturing processes. These processes include extrusion, isostatic pressing, and injection molding. The finishing of alumina ceramics can be done using laser machining, precision grinding, or other processes.
However, alumina injection molding remains the most suitable alumina manufacturing process due to various possibilities for component design. This allows alumina ceramic manufacturers to cater to the varying needs of clients from different industries.
