Semi-Circular Ceramic Rod With Thread 99% Alumina Ceramics

Alumina is one of the most widely used advanced ceramics, and is made from aluminum oxide. Alumina’s high ionic interatomic bond makes it chemically very stable, thereby making it a good electrical insulator. Further it is extremely resistant to wear and corrosion and has a high mechanical strength. Due to all these qualities, alumina ceramics are used to manufacture ceramic components used in a wide range of applications, such as electronics, semiconductor components, pump components, electrical insulators, and automotive sensors.

Alumina ceramics can be manufactured through several different types of processes, including isotactic pressing, injection molding, or extrusion. Finishing can be accomplished by precision grinding and lapping, laser machining, or a variety of other processes.
