Alumina is the most well-known and most commonly used fine ceramic material. It has the same sintered crystal body as sapphire and ruby. It has been used for decades in electrical components for its high electrical insulation, and is widely used in mechanical parts for its high strength, and corrosion- and wear-resistance.
- Mechanical properties: High strength and high hardness.
- Thermal properties: High heat resistance and high thermal conductivity.
-Other properties: High electrical insulation, high corrosion resistance and biocompatibility.
