Explanations of the characteristics of Aluminum Oxide.
Aluminum Oxide (Al2O3) is the most well known and widely used material in numerous engineering ceramics. So its price is the lowest of all ceramic materials.
Generally it is also referred to as Alumina.
It possesses strong ionic inter-atomic bonding. Thus it has high hardness (next position of diamonds), wear resistance, superior electric insulation and chemical stability.
And it has good heat resistance (1,500°C), plasma resistance,
excellent dielectric properties and is an electrical insulator. On the other hand, it has a relatively high thermal conductivity (40 W/mk).
But its properties of heat shock resistance and fracture toughness are weaker than the other ceramics.
Other properties are excellent size, shape capability, translucency etc.
Industrial mechanical parts:
Parts of semiconductor, liquid crystal and solar panel production device.
Machine tools. Parts of effluent gas resolution devices.
Medical and dental tools.
Standard plate of x-y table, Insulator, Refractory, Abrasive (polishing materials) etc.
