Description
Alumina is the most widely used technical ceramic and is the material of choice in about 80% of engineering applications due to its excellent combination of properties. Fired at over 1600°C (2910°F) to give a fully dense ceramic, alumina exhibits high mechanical strength and stiffness that is retained at elevated temperature.
